JSON-Utils

Text Diff

Compare any two blocks of text line by line: configuration files, log excerpts, generated code, or prose. Lines are matched with a longest common subsequence diff, so moves show as a removal plus an addition, and unchanged context stays visible.

Frequently asked questions

How is this different from JSON Diff?

Text Diff is line based and works on any text. JSON Diff understands JSON structure and compares by path, ignoring formatting entirely.

Is it character level?

No, it is line level, which is what most config and code comparisons need.
