Compare Sheets for Google Sheets

This is a set of 3 add-ons for Google Sheets that compare your columns and sheets for duplicate and unique data.

Compare Sheets for Duplicates tool compares multiple sheets against the main one for duplicate (or unique) rows in one go. The add-on marks them with color or in a status column in the sheets of your choice (main, other compared sheets, or all sheets), copies or moves duplicate rows to a required sheet, clears records from such rows, or deletes the rows completely.

Compare Sheets Cell by Cell tool compares multiple Google sheets against your main one for differences. It looks into each and every cell in the main sheet and tests their contents against the same cells in every other sheet. You'll see these differences highlighted and labeled in a status column.

Compare Columns lets you compare two columns of data in just one step & a few clicks. User-friendly interface, fast & accurate results – what else is there to wish for? :)

There's no native way to compare in Google Sheets. You need to incorporate functions & conditional formatting and tweak them to your needs.

Our add-on leads you all the way through the user-friendly steps letting you control everything by simply ticking off the required checkboxes.

Both add-ons can work with more than two columns or sheets at a time. Compare as many sheets as you need :)

Not at all. You are free to add other spreadsheets from Drive right to the add-on and work with multiple sheets from all those different files.

Run Compare sheets for duplicates from the Extensions menu and follow these steps:

1. Select all sheets you want to compare.
2. Pick the main sheet among them.
3. Choose what to find:
   • Duplicates
   • Uniques
4. Select the columns to check.
5. Decide what to do with the found values.
6. Click Compare.

See a more detailed description here.

If you say so :) There's a special option on the last step that lets you apply the action to the found duplicates or uniques on the main sheet only, on all sheets but the main one, or on all sheets altogether.

Open Compare sheets cell by cell and do the following:

1. Select all required sheets.
2. Identify your main sheet.
3. Choose what to do with differences:
   • Show them on each sheet
   • Place everything into full report
4. Click Compare.

See a more detailed description here.

Only distinctions in records (cell contents).

If the record in a cell varies between the sheets, the cell is considered to be different.

If all cells in a row are different, it means this row doesn't have even a partial equivalent in other sheets. In this case, it's marked as a completely unique row.

Yes. Although it doesn't compare all Google sheets against each other. It weighs each selected sheet with the main one individually. So the colors will show the differences between the main sheet and every other sheet.

1. Open the add-on.
2. Select the range containing the columns of interest.
3. Set one column as the main one, and another as a compared one.
4. Choose the values to find: duplicate or unique.
5. Decide what to do with the results.
6. Click Compare.

No, not with this tool. This one is created specifically to work with columns on the same tab. For multiple tabs, use Compare sheets for duplicates tool instead.

Not at the moment. Let us know if you'd like to see this little tool enhanced. And meanwhile, use the Compare sheets for duplicates tool instead.

If you say so. There's a special setting that controls this behavior. The same goes for the text case & column headers.
