Text & CSV comparison

Compare changes between two texts or differences between CSV rows matched by key.

Three steps

1. Choose text or CSV comparison and enter both sides.
2. Select whitespace/case options or the CSV key column.
3. Review differences and scope notices, then save JSON.

Supported features and limits

Preserves original strings and indicates exact comparison or coarse fallback for large inputs.

Text: 1 MiB and 2,000 physical textarea lines per side. CSV: 10,000 rows and 100 columns per side; duplicate or missing keys are rejected.

If something goes wrong

Check for missing or duplicate CSV keys. If large text uses coarse comparison, compare smaller sections for finer detail.
