File Diff Guide
File Diff compares two plain-text documents line by line and highlights additions and deletions. SheetEdit Tools provides a free online tool. All processing runs in your browser; no data is uploaded to our servers.
When to use it
- Logs and configs: Compare two versions of
.txt,.md,.log, or other text files. - Code or markup: Quick side-by-side review without parsing JSON (unlike JSON Diff).
- Paste workflow: Paste “before” and “after” text from any source and compare immediately.
Features
- Line-level diff: Aligned left/right view with red (removed) and green (added) lines.
- Edit mode: Return to dual editors, adjust text, and compare again.
- Open files: Load text from your device (max 2 MB per file).
Tips
- Line endings are normalized so Windows (CRLF) and Unix (LF) behave consistently.
- For structured JSON, use JSON Diff to compare after pretty-printing.
- Very large files may feel slow in the browser; trim to the relevant section when possible.
