How it works
Drop your original file on the left and your updated file on the right. The tool compares each row by position and each cell by column position. Summary counts cover every row. The table shows up to 200 rows for the selected filter.
When to compare two CSVs
Teams compare CSVs to check a fresh export, review edits to a shared file, or confirm that rows and values stayed intact. This tool presents those changes as rows and columns, so they are easy to scan.
After you review the diff, you can chat with one CSV or TSV and ask about up to its first 200 lines after the header. Files from this page do not carry over, so you will need to upload the file again. You can also view a CSV on its own by selecting it again.
