You can compare two sheets or two versions of a sheet by aligning them with each other.

To compare sheets:

1. Open the first sheet.

2. On the top toolbar, click Compare sheets .

3. Select the second sheet and its version. You can select another version of the first sheet.

4. Click Compare sheets.

   This adds the second sheet overlapped with the first one (without the second sheet’s issues or markup).

   The sheet colors change to the following:

   • Blue. Parts that are present only on the first sheet.

   • Red. Parts that are present only on the second sheet.

   • Black. Parts that are present on both sheets.

   

   The comparison menu on the left provides the following options:

   Option	Description
   Align sheets	Align sheets manually. You can drag the first sheet or move it precisely using the arrows in the lower-right corner. To undo the changes, in the upper-right corner, click Reset. To apply the changes, click Done.
   Overlay view	Switch from the single-sheet view to the overlay view.
   Single-sheet view	Switch from the overlay view to the single-sheet view. In the single-sheet view, you can switch between the sheets by clicking them. Both sheets display the issues or markup that belong to the first sheet.
   	Change the sheet transparency on the overlay view. When the slider is in the center, both sheets are displayed in full color. When you move the slider to the left, this increases the transparency of the red sheet. When you move the slider to the right, this increases the transparency of the blue sheet.
   Switch	Switch between the sheets. In the overlay view, this makes one of the sheets transparent to show the other one.
