File Diff

Quick answer: Compare two text files or pastes line by line to see exactly what changed. Open 文件对比 — everything runs locally in your browser, and files never leave your device.

Steps

1. Paste version A and version B on either side.
2. Read the line-level diff: removals left, additions right.
3. Enable character-level view for in-line edits.

Important notes

• Binary files (docx/xlsx) must be exported to text or CSV first.
• Trim to the relevant section before diffing large files — noise hides signal.

Common questions

Can I diff PDFs? Convert to TXT first; for layout-level comparison use PDF Compare.

Export the diff? Copy the text or screenshot it.

When to use this

For contract review, diff after converting both versions to text — wording changes surface while layout noise stays out of the way.
