Key takeaways

  • Diff highlights what changed—perfect for YAML/JSON snippets.
  • Pair with JSON Formatter so both sides are comparable.

A simple review loop

Normalize formatting on both sides so whitespace noise does not hide real edits.

Paste before/after snippets into Diff Checker and scan for unexpected hunks.

Pair with other tools

If only keys moved, JSON Formatter helps stabilize ordering for a fair text diff.

FAQ

Does diff understand JSON semantically?

Text diff compares lines; for semantic JSON diff use specialized tools in addition.

Large files?

Focus on relevant sections or split inputs—diff is best for reviewable chunks.
