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.

Често задавани въпроси

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.
