Excel 2021 for Windows allows you to collaboratively work with others and analyze data easily with new Excel capabilities including co-authoring, Dynamic Arrays, XLOOKUP, and LET functions.
Co-authoring You and your colleagues can open and work on the same Excel workbook. This is called co-authoring. When you co-author, you can see each other's changes quickly - in a matter of seconds.
Better collaboration with modern comments Have control of when you send comments to your co-authors and be productive with a consistent commenting experience in your workbooks and other Office apps.
Know who's in your workbook See who else is working along with you and where they are in the workbook.
XLOOKUP function Row by row, find anything you need in a table or range with XLOOKUP. Return exact matches by default - there's no need to specify.
LET function The LET function assigns names to calculation results. This allows storing intermediate calculations, values, or defining names inside a formula. These names only apply within the scope of the LET function.
Dynamic arrays Write one formula and return an array of values. Expedite calculations and insights with six more new functions: FILTER, SORT, SORTBY, UNIQUE, SEQUENCE, and RANDARRAY.
XMATCH function The XMATCH function searches for a specified item in an array or range of cells, and then returns the item's relative position. You can also use XMATCH to return a value in an array.
Performance improvements Experience improved performance, stability, and speed across Excel. Get faster calculations from common Excel functions like SUMIF, COUNTIF, and AVERAGEIF.
Unhide many sheets at the same time No need to unhide one sheet at a time anymore - unhide multiple hidden sheets at once.
