Diff Tools

Compare two text blocks or JSON documents side by side. Get a unified line diff plus structural change summaries for JSON — useful for configs, API responses, and code review.

Diff Tools

• Text Diff

  Paste original and modified text to see a line-by-line unified diff. One panel may be left empty to treat all lines as added or removed. Combined input limit is 500 KB.

• JSON Diff

  Paste original and modified JSON to see structural changes (top-level keys, root arrays) and a formatted unified diff. Key order is ignored — objects are compared after sorting keys. Invalid JSON in either panel is reported before diffing.
