Track Changes is a powerful feature of Microsoft Excel that allows you to keep track of the changes made to a workbook. It works by highlighting the cells that have been changed and adding notes detailing what was changed and by whom. This feature is particularly useful when collaborating on a workbook with others, as it helps everyone stay on the same page and prevents errors and redundancies.

Here is a step-by-step guide on how to use Track Changes in Microsoft Excel:

Step 1: Open the workbook you want to track changes in and select the Review tab from the ribbon.

Step 2: Click the Track Changes button in the Changes group. This will open the Track Changes dialog box.

Step 3: In the Track Changes dialog box, you can choose to track changes to just selected cells or to the entire workbook. You can also choose which types of changes you want to track, such as changes to cells, formatting, or comments.

Step 4: In the Track Changes dialog box, you can also specify who you want to track changes for. You can choose to track changes made by everyone, by specific users, or by yourself only.

Step 5: Once you have chosen your tracking options, click OK to begin tracking changes.

Step 6: As changes are made to the workbook, Excel will highlight the cells that have been changed and add a note to the cell with details on the change. The note will include the user who made the change, the date and time it was made, and any comments they added.

Step 7: To review the changes that have been made, you can click on a highlighted cell to view the note. You can also use the Accept and Reject buttons in the Changes group to accept or reject changes made by other users.

Step 8: Once you are finished reviewing the changes, you can stop tracking changes by clicking the Track Changes button and selecting Stop Tracking Changes. This will remove the highlighting and notes from the workbook.
