How does in-browser CSV to JSON conversion work?

The parser tokenizes tabular CSV data directly in local browser memory according to the RFC 4180 specification. It automatically detects separators (comma, semicolon, tab, pipe), handles multi-line quoted fields, and converts data into a clean JSON array of objects.

Are my CSV files or spreadsheets uploaded to any remote server?

No. All conversion and parsing routines run 100% client-side in your browser memory sandbox. Zero bytes of data are sent over the network, ensuring complete confidentiality for customer databases, pricing lists, and internal spreadsheets.

Can I convert JSON arrays back into CSV spreadsheets?

Yes. Toggle to "JSON ➔ CSV" mode to transform JSON object arrays or arrays of arrays into RFC 4180 compliant CSV text, with custom delimiter support and header configuration.

Does the converter automatically detect numeric and boolean data types?

Yes. When "Auto-parse Numbers & Booleans" is active, numeric values, floats, true/false booleans, and nulls are converted to their native JavaScript types. Strings with leading zeros (like postal codes or phone numbers) are preserved as strings.
