Integration & B2B
CSV ↔ JSON converter
Convert flat files to JSON and back, with a real RFC 4180 parser — quoted delimiters, embedded newlines and leading zeros all survive.
Import or drop one UTF-8 .csv, .tsv or .json file, up to 1 MiB. Clear retains settings; Reset restores the default direction, sample and options.
5 physical lines · 179 Unicode characters · 179 UTF-8 bytes
1 physical line · 0 Unicode characters · 0 UTF-8 bytes
Enter data or import a UTF-8 file, then convert.
Save and restore this workspace
Save downloads session JSON containing input and settings. Restore validates the whole file before replacing the workspace. Session input is limited to 1 MiB; serialized files allow additional space for JSON escaping. Converted output is recalculated after restore. No automatic data storage occurs.
Expanded conversions are limited to 500,000 cells and 8 MiB of output. A real RFC 4180 parser handles quoted delimiters, embedded newlines and escaped quotes. Type inference is off by default; leading zeros remain text. Files and calculations are processed locally. Downloaded sessions contain your input. Input sharing happens only when you explicitly choose an input-containing link; favourites store only this tool's ID.
