We are excited to announce that LAMBDA and LAMBDA helper functions are now generally available to anyone using Production: Current Channel builds of Excel. In conjunction with LAMBDA going to production, we are also announcing the release of a new add-in, the advanced formula environment, sponsored by the Microsoft Garage and Microsoft Research, which allows for improved formula authoring experiences and easy import/export of named LAMBDAs.
Thanks to all of our Insiders for using the LAMBDA functions and giving us feedback! As a result we’ve also made a few changes that we’ll outline below in addition to talking about the advanced formula authoring environment, a Microsoft Garage project.
Let’s start with a quick example.
IFBLANK
A task I regularly encounter is replacing certain values in a dataset, such as errors or blanks cells. Excel provides IFERROR to replace error values, but there is no function to replace blank cells. Fortunately, with LAMBDA, we can define our own function, IFBLANK.
Instead of authoring this in the grid and then importing to the name manager, I will instead author this in the new formula environment and then sync it to the workbook to make use of it in the grid.
In today’s scenario I am trying to create a quick count of the meals that have been requested for a dinner party I am hosting.
Without IFBLANK, Excel, by default returns a 0 for blanks. I could work around this but I also need to get a count of orders which I will do using MAP and REDUCE to author one formula so I can get updated counts as I continue to get more responses from guests.
Here’s the formula I used for the counts:
=MAP(D4#, LAMBDA(meal, REDUCE(0, IFBLANK(Table14[Meal Preference], B1), LAMBDA(meal_count, preference, IF(meal=preference, meal_count+1, meal_count)))))
Lets go over some improvements and changes we have made on our journey through Insiders to the LAMBDA feature in general.
Changes made to LAMBDA
Function tooltips
We have added support for function tooltips for named LAMBDAs in addition to auto-completing the open parentheses character when calling these functions. In other words, calling a function defined using a LAMBDA is exactly the same as calling a native function.
Recursion limit increase
We have upped the limit of recursion by 16 times its original limit. In this example, the text string is 3200 characters long and would have previously returned a #NUM when called with a LAMBDA that recursively reverses a text string.
LAMBDA helper function outputs
We changed the way that the LAMBDA helper functions handle arrays of references.
Previously when a LAMBDA helper function returned an array and the associated LAMBDA returns a single cell, a #CALC error would be returned. We have changed this to automatically return the cell value as the output of the LAMBDA function.
In this example, Excel would have returned a #CALC but now will return the results.
Advanced formula environment, a Microsoft Garage project
Today we are introducing a new tool to aid in the authoring of more complex named formulas. The advanced formula environment is a space where we are hoping to experiment and explore new and different methods for authoring formulas with special functionality designed with LAMBDAs and LET in mind.
Key features of the new tool:
- Advanced formula authoring capabilities found in modern IDEs
- Intellisense
- Commenting
- Inline errors
- Auto tabulation
- Code collapse
- And more…
- Undo/redo of formula edits within the manager
- Namespaces to allow for groups of named functions
- Import and export functionality
- Text and GitHub Gist import
- Different views to filter your names and edit in a single location
The environment is available on all platforms where Office Add-ins are available (Mac, Windows, Web)
Let’s take a look at some of the functionality so you can get started with managing and editing your new and pre-existing named functions!
Manager and Editor Views
There are two major views contained within the advanced formula environment, Manager and Editor.
Manager
The Manager is where you will see all of your names with their own individual cards and associated quick actions. Much like the Name Manager but with more functionality.
 |
Edit the name |
 |
Rename the formula |
 |
Delete the entry |
 |
Export the definition for sharing |
Editor
The Editor is where you can go to edit all entries within the workbook or create new namespaces for collections of formulas.
This is where I usually go when I want to dive in to create more complex functions as you get the full version of the editor in this view and can create multiple names sequentially.
The workbook section contains all names which are not attached to a given sheet but instead are saved globally in the workbook.
Some of my favorite pieces of functionality are the ability to easily add new lines, tabulate sections of the formula while also being able to comment out pieces of my formula that I might be working on, or collapse definitions so I can more easily dig into specific areas. Not to mention, if I change my mind later, I can easily undo/redo any changes I am actively working on.
Here’s another example I made for a chess game I have been building for fun in Excel.
Importing
The advanced formula environment can import definitions into the manager. You can important individual definitions as well as libraries of definitions via text or through GitHub Gists.
The main entry point for importing can be found by selecting the action in the actions bar. The main entry point defaults to “From URL” but the dropdown reveals the “From text” option.
If you’d like to try out this functionality yourself I am including a gist with some of the examples I created today on top of additional LAMBDAs I have used in prior posts. I think this is a better way to share than having you copy/paste from a blog post, so lets be the first to try it out!
aka.ms/LAMBDAGist (make sure to use the URL you are redirected to as the add-in doesn’t let you use non gist paths)
We look forward to the libraries of LAMBDAs the community produces and hearing from you all about what does and doesn’t work in this new environment we have created.
Feedback
We are actively looking for feedback on the experience and would invite you to provide feedback either through techcommunity or by going to this github repository.

A joint collaboration
The last thing I would like to mention is that all of this was done as a joint collaboration between Microsoft Research and Excel Engineering. It’s been a blast building out all the experiences you see today and it wouldn’t have been possible without the brilliant researchers at Microsoft Research Cambridge.

It’s a challenging time in software security; migration to the modern cloud, the largest number of remote workers ever, and a global pandemic impacting staffing and supply chains all contribute to changes in organizations. Unfortunately, these changes also give bad actors opportunities to exploit organizations:
“Cybercriminals are targeting and attacking all sectors of critical infrastructure, including healthcare and public health, information technology (IT), financial services, and energy sectors. Ransomware attacks are increasingly successful, crippling governments and businesses, and the profits from these attacks are soaring.”
– Microsoft Digital Defense Report, Oct 2021
|
For years Microsoft Office has shipped powerful automation capabilities called active content, the most common kind are macros. While we provided a notification bar to warn users about these macros, users could still decide to enable the macros by clicking a button. Bad actors send macros in Office files to end users who unknowingly enable them, malicious payloads are delivered, and the impact can be severe including malware, compromised identity, data loss, and remote access. See more in this blog post.
“A wide range of threat actors continue to target our customers by sending documents and luring them into enabling malicious macro code. Usually, the malicious code is part of a document that originates from the internet (email attachment, link, internet download, etc.). Once enabled, the malicious code gains access to the identity, documents, and network of the person who enabled it.”
– Tom Gallagher, Partner Group Engineering Manager, Office Security
|
For the protection of our customers, we need to make it more difficult to enable macros in files obtained from the internet.
Changing Default Behavior
We’re introducing a default change for five Office apps that run macros:
VBA macros obtained from the internet will now be blocked by default.
For macros in files obtained from the internet, users will no longer be able to enable content with a click of a button. A message bar will appear for users notifying them with a button to learn more. The default is more secure and is expected to keep more users safe including home users and information workers in managed organizations.
“We will continue to adjust our user experience for macros, as we’ve done here, to make it more difficult to trick users into running malicious code via social engineering while maintaining a path for legitimate macros to be enabled where appropriate via Trusted Publishers and/or Trusted Locations.”
– Tristan Davis, Partner Group Program Manager, Office Platform
|
This change only affects Office on devices running Windows and only affects the following applications: Access, Excel, PowerPoint, Visio, and Word. The change will begin rolling out in Version 2203, starting with Current Channel (Preview) in early April 2022. Later, the change will be available in the other update channels, such as Current Channel, Monthly Enterprise Channel, and Semi-Annual Enterprise Channel.
At a future date to be determined, we also plan to make this change to Office LTSC, Office 2021, Office 2019, Office 2016, and Office 2013.
End User Experience
Once a user opens an attachment or downloads from the internet an untrusted Office file containing macros, a message bar displays a Security Risk that the file contains Visual Basic for Applications (VBA) macros obtained from the internet with a Learn More button.
A message bar displays a Security Risk showing blocked VBA macros from the internet
The Learn More button goes to an article for end users and information workers that contains information about the security risk of bad actors using macros, safe practices to prevent phishing & malware, and instructions on how to enable these macros by saving the file and removing the Mark of the Web (MOTW).
What is Mark of the Web (MOTW)?
The MOTW is an attribute added to files by Windows when it is sourced from an untrusted location (Internet or Restricted Zone). The files must be saved to a NTFS file system, the MOTW is not added to files on FAT32 formatted devices.
IT Administrator Options
This chart shows the evaluation flow for Office files with VBA macros and MOTW:

Organizations can use the “Block macros from running in Office files from the Internet” policy to prevent users from inadvertently opening files from the internet that contain macros. Microsoft recommends enabling this policy, and if you do enable it, your organization won’t be affected by this default change.
“Setting policy is a powerful tool for IT Admins to protect their organizations. For years we’ve recommended blocking macros obtained from the internet in our security baselines, and many customers have done so. I’m pleased Microsoft is taking the next step to securing everyone with this policy by default!”
– Hani Saliba, Partner Director of Engineering, Office Calc

Additionally, there are two other options to know your files are safe:
- Opening files from a Trusted Location
- Opening files with digitally signed macros and providing the certificate to the user, who then installs it as a Trusted Publisher on their local machine

SQL Server uses 3 types of affinity to control where the SQL Server worker threads execute. Before explaining the different scheduler affinity types let me clarify some terminology.
Node Types
SQL Server makes a specific distinction between scheduling and memory nodes.
Scheduling nodes: sys.dm_os_nodes
Memory nodes: sys.dm_os_memory_nodes
A scheduling node is a used to group a set of SQLOS schedulers. The scheduling node must :
- Remain within a single memory node.
- Can be configured to use a subset of the CPUs presented by the OS from the same memory node.
For example: A memory node with 64 CPUs is a complete, Operating System, scheduler group. SQL Server may choose to divide the memory node allowing for better partitioning and performance. The Soft Numa feature may take the 64 CPUs and create 8 scheduler nodes, each managing 8 CPUs or 4 scheduler nodes managing 16 CPUs, etc. The decision is performance driven.
A memory node represents the memory associated with a group of CPUs from the physical hardware. SQL Server aligns schedulers and other partitioned structures with the memory node to reduce access to remote, NUMA node memory when possible. A memory node may have 1 or more scheduling nodes, but a scheduling node can only be assigned to a single memory node.

Many organizations want to provide Microsoft Teams to their employees, but not in a “no strings attached” way. With our customers, we often see the need for a provisioning solution, so people aren’t creating teams without thinking.
With “traditional” team creation (i.e. the built-in “Create a team” functionality) a lot of the teams that get created don’t leverage the full potential that Microsoft Teams has to offer. When a team is created as a blank slate the owner has to know what the possibilities are and how to set it up, to create a team fit for their need. On the other hand, templates don’t satisfy users’ needs either. There is no such thing as “one size fits all”. Again, to modify it, the user needs to have a certain level of knowledge.
A different approach
To tackle these two challenges when it comes to Microsoft Teams provisioning, we had a vision of a provisioning solution where we blend learning with the process of creating your team. We provide the why, the user decides the what, and the tool takes care of the how. This is how ProvisionGenie ? was born.
ProvisionGenie is a tool that guides the user through the creation process. Someone who desires a team can start up the application from inside Microsoft Teams, so they stay in the flow of their work. They will need to provide some basic information such as the name, description, and members of the team. Then the tool continues with some of the essential building blocks of a great Microsoft Teams team: channels, lists and libraries. The user gets information on why they would care about these things, and they can customize them to their liking.
An enterprise-ready solution
ProvisionGenie is built with companies in mind: a scalable database, a reliable workflow engine and a Teams-like user interface.
The data is stored in Microsoft Dataverse, the relational database built into the Power Platform that allows for advanced security scenarios. In the current version, we focus on the front-end for the users of the application. By storing our data in Dataverse however, we can expand this relatively easily in the future with a model-driven application for administrators.
Azure Logic Apps take care of the workflows and logic of creating the team with its resources. Logic Apps not only offer better permission management, they can also be deployed across tenants automatically. They are more scalable and therefore performant compared to their low-code counterpart Power Automate.
Finally, a Power Apps canvas app is used to create a beautiful user interface that fits seamlessly into Microsoft Teams. With a canvas app, there is full control over the look and feel of the UI. The canvas app provides the different options to the user and saves the configuration in Dataverse. There is no direct link between the canvas app and the Logic Apps.
A community driven initiative
ProvisionGenie was born out of the collaboration of two community members because we wanted to provide a different solution for Microsoft Teams provisioning.
We decided quite early in the process that we wanted this to be a solution for the community, by the community. Therefore, this is an open-source project which you can find on GitHub (<<link>>) and to which everyone is welcome to contribute.
