CSV Diff Checker — Compare Two CSV Files
Quick Answer: Paste two CSV files to compare row by row. The diff highlights added rows, deleted rows, and cells that changed. Useful for comparing data exports, finding changes between database snapshots, and validating ETL transformations.
FAQ
How does CSV diff work?
Rows are compared line by line. If you have a unique ID column, the tool can match rows by ID to detect moved rows (not just added/deleted).
Can it handle large CSV files?
It handles files with thousands of rows in the browser. For very large CSVs (100K+ rows), consider command-line tools like csvdiff or diff-csv.
