FEATURES
Use the lookup function in Excel LTSC 2021. Find a record by code or name and return a related value from another range, such as a price or product category.
Work with a dark document canvas. Adjust the working page's appearance for comfortable reading and editing without changing the document's color scheme.
Open and save files using the updated OpenDocument standard. This helps exchange files with applications that support OpenDocument. Check complex formatting separately after conversion.
Deploy a release without new app features being added later. A predictable toolset suits workplaces that need to maintain a consistent environment and previously tested workflows.
Get a set of results from one formula: filter rows with FILTER, sort with SORT and return unique values with UNIQUE. The result size changes with the data.
Assign names to intermediate results within an Excel formula. This makes complex calculations easier to read and lets you reuse parts without duplicating expressions.
Find an item's position in an Excel range with an exact or approximate match. Use the result in more complex data lookup and matching formulas.
Check that your document, Excel workbook, or presentation is accessible to users of assistive technologies. Fix any issues found before sharing the materials.

A personal subscription does not replace enterprise LTSC usage rights. — Ask your administrator to check the license and activation method before deployment.
Back up your documents and confirm the release’s requirements and support status. — This release is no longer supported. Use it only where a licensed legacy workflow requires it, keep backups and plan a move to supported software.
