Text Diff
TextCompare two text blocks line by line
Not everything worth diffing lives in a git repo. A changelog draft, a documentation edit, or a find-and-replace across a large text block all benefit from a quick line-by-line comparison without setting one up. This tool highlights additions and deletions between two pasted blocks of plain text, with an option to ignore whitespace-only differences when two lines look identical but still get flagged. It's a general-purpose text comparison, not a git wrapper, so it won't understand history, blame, or merge conflicts; for structured JSON specifically, use JSON Diff or JSON Path Diff instead, since a line-based diff on formatted JSON will flag re-indentation as a change even when nothing meaningful moved.
How to use Text Diff
- 1.Paste two versions of a text file or config to see line-by-line additions and deletions highlighted side by side.
- 2.Compare two versions of a commit message, changelog, or documentation draft before merging to catch unintended changes.
- 3.Use it to sanity-check a find-and-replace across a large text block by diffing the before and after.
