Diff & Compare

Compare text, JSON and code side by side.

• Text Diff Checker

  Compare two blocks of text line by line and get a unified diff plus added/removed line counts. Nothing is uploaded — the comparison runs in your browser.

• JSON Diff Checker

  Compare two JSON documents semantically — key order never matters — and see every changed, added or removed path in a table. Runs in your browser.

• CSV Diff Tool

  Compare two CSV exports row by row, matched on a key column of your choice, and see exactly which rows were added, removed or changed. Nothing is uploaded.
