Text Diff & Compare

JSON Compare parses JSON and diffs the structure. This tool treats input as plain text lines — ideal for logs, configs, prose, or any non-JSON content.

When one line was removed and another added at the same logical position, they are grouped as a modification (amber) so you can see a replacement at a glance.

They change how lines are compared: whitespace mode collapses runs of spaces and trims ends before matching; ignore case lowercases text for comparison only — the original text is still shown in the output.

Yes. Use the Upload button above each editor to load a text file into Original or Modified, then click Compare.
