CSV to JSON & JSON to CSV
Paste a spreadsheet export or a JSON array. We detect commas, European semicolons (;) and tabs, keep quoted fields, and convert both ways without uploading customer data.
CSV to JSON & JSON to CSV — no upload
“CSV to JSON” is one of the highest-volume converter searches worldwide. Spreadsheets in Germany, France and Spain often export with semicolons (;). This converter auto-detects commas, semicolons and tabs, keeps quoted fields, and never uploads your customer lists.
- CSV → JSON for APIs, Postman and Base64 payloads.
- JSON → CSV for Excel / LibreOffice.
- Then pretty-print with the JSON formatter or convert YAML ↔ JSON.
Frequently asked questions
Why does my EU CSV use semicolons?
In many European locales Excel uses ";" because "," is the decimal separator. Choose Auto-detect or ";" in the delimiter menu.
Do you upload my CSV?
No. Parsing runs entirely in your browser.
