Five common mistakes
- Converting in the wrong direction — going from lossy back to lossless doesn't recover the lost data.
- Re-encoding the same file twice — quality drops each pass.
- Wrong quality preset — aggressive for archival, conservative for web. Easy to mix up.
- Forgetting to verify the output — open it, check it looks right, before committing.
- Stripping metadata you needed — copyright, color profile, timestamps. Worth knowing which ones to keep.

Frequently asked questions
Can I convert in bulk?
Yes — drop multiple files; JSON to CSV processes them all with the same settings.
What JSON variants does JSON to CSV support?
JSON to CSV handles the standard variants of JSON that mainstream software produces. Niche or obsolete variants may need a converter that handles legacy formats first.
Will the CSV look as good as the JSON?
For most content, yes — JSON to CSV's defaults target visually indistinguishable output.
Will the file size go down?
Usually yes — CSV typically compresses better than JSON for equivalent visible quality.
