How do I convert CSV to JSON?

Paste your CSV data in the input field, ensure 'First row is header' is checked if applicable, and the JSON output will be generated automatically. Each row becomes a JSON object.

Can I convert JSON back to CSV?

Yes! Switch to 'JSON to CSV' mode and paste your JSON array. The tool will generate a CSV with headers from the JSON object keys.

What delimiters are supported?

We support comma (,), semicolon (;), tab, and pipe (|) delimiters. Choose the one that matches your CSV format from the delimiter dropdown.

How are quoted fields handled?

Our parser properly handles quoted fields, including fields containing commas, newlines, and escaped quotes (double quotes within quoted fields).

Is there a row limit?

There's no hard limit, but for best performance we recommend files under 10,000 rows. The table preview shows the first 20 rows.

What is the CSV Tools converter?

Written and maintained by the BitConvert team · Feb 27, 2026

CSV Tools helps you view, clean, and convert tabular data between CSV and JSON. Paste raw CSV and the tool parses it into a live table preview and a structured JSON array where each row becomes an object keyed by the header columns. You can also work in reverse, turning a JSON array back into properly delimited CSV.

The parser respects real-world CSV quirks: quoted fields, commas and line breaks inside quotes, and escaped double quotes. You can pick the delimiter that matches your file, whether that is a comma, semicolon, tab, or pipe, and toggle whether the first row is treated as a header. Everything is processed locally in your browser, so spreadsheets exported from work systems never leave your device.

Common Use Cases

Turn a spreadsheet export into a JSON array to feed an API or seed a database. Convert a JSON dataset back to CSV so it opens cleanly in Excel or Google Sheets.
