Frequently Asked Questions

Is it safe to convert CSV to JSON here?

Absolutely. Your CSV data never leaves your browser. All parsing and conversion runs client-side using JavaScript, so no data is uploaded to any server. Your files remain completely private on your device.

What delimiters does the converter support?

Our CSV to JSON converter supports four delimiter types: comma (standard CSV), semicolon (common in European formats), tab (TSV files), and pipe. Select the appropriate delimiter before converting for accurate results.

Can I convert CSV files with headers?

Yes. When the 'First row as headers' option is enabled (the default), the first row of your CSV is used as keys in the resulting JSON objects. Disable it to get arrays of values instead of objects.

Does it handle special characters and quoted fields?

Yes. The converter correctly handles quoted fields, commas inside quotes, newlines within fields, and escaped characters following the CSV standard (RFC 4180). Complex spreadsheet exports convert accurately.

Is there a file size limit?

There is no hard file size limit. Since all processing happens in your browser, performance depends on your device memory. Most CSV files up to several megabytes convert smoothly on modern devices.
