Preserving metadata when converting CSV to JSON
What metadata survives the conversion in CSV to JSON, and what gets stripped (and why that matters).
CSV and JSON both have their place — but when you need one and you've got the other, CSV to JSON is the cleanest way to convert between them in your browser.

What metadata survives the conversion
Most embedded metadata (EXIF for images, ID3 for audio, etc.) is preservable across the conversion, but CSV to JSON defaults to stripping it for privacy. If you specifically need to keep metadata, there's a toggle.
Stripped metadata can include: GPS location, camera serial number, edit history, original filename, capture time. Strip by default unless you have a reason to keep it.

Frequently asked questions
Will the file size go down?
Usually yes — JSON typically compresses better than CSV for equivalent visible quality.
Does CSV to JSON upload my CSV file?
No. CSV to JSON converts in your browser using WebAssembly. The file stays on your device.
Can I convert in bulk?
Yes — drop multiple files; CSV to JSON processes them all with the same settings.
What CSV variants does CSV to JSON support?
CSV to JSON handles the standard variants of CSV that mainstream software produces. Niche or obsolete variants may need a converter that handles legacy formats first.
