In Excel track changes is a useful feature. Track changes in Excel and use the comments feature when proofreading workbooks.
Let's say someone asked you to proofread or collaborate on a workbook. If you had a printed copy, you might use a red pen to edit cell data, mark spelling errors, or add comments in the margins. Excel allows you to do all of these things electronically using the Track Changes and Comments features.
Optional: Download our practice workbook.
When you turn on the Track Changes feature, every cell you edit will be highlighted with a unique border and indicator. Selecting a marked cell will show the details of the change. This allows you and other reviewers to see what's been changed before accepting the revisions permanently.
There are some changes Excel cannot track. Before using this feature, you may want to review Microsoft's list of changes that Excel does not track or highlight.
You cannot use Track Changes if your workbook includes tables. To remove a table, select it, click the Design tab, then click Convert to Range.
When you turn on Track Changes, your workbook will be shared automatically. Shared workbooks are designed to be stored where other users can access and edit the workbook at the same time, such as a network. However, you can also track changes in a local or personal copy, as seen throughout this lesson.
You can also view changes on a new worksheet, sometimes called the Tracked Changes history. The history lists everything in your worksheet that has been changed, including the old value (previous cell content) and the new value (current cell content).
To remove the History worksheet from your workbook, you can either save your workbook again or uncheck the box next to List changes on a new sheet in the Highlight Changes dialog box.
