About CSV ↔ JSON
Change a simple table into JSON, or turn a list of JSON records into a CSV file you can use elsewhere.
How to use it
- Choose CSV → JSON or JSON → CSV.
- Paste comma-delimited CSV with a header row, or a nonempty JSON array of objects.
- Run the tool, inspect the result and any spreadsheet-safety warning, then copy or download.
Good to know
- CSV needs unique, nonempty header names; parsed cell values remain strings. JSON export uses the union of object keys, with missing or null values becoming empty cells.
- Formula-like cells are preserved and flagged. Import untrusted CSV as plain text in spreadsheet software to avoid formula execution.
- Quote large numeric identifiers in JSON to preserve exact values. Unsafe integers are rejected, and nested objects become JSON text inside cells.
