Frequently Asked Questions

Does the CSV need headers?

Yes. The first row of your CSV is treated as column headers, which become the keys in each JSON object. Without headers, the converter cannot name the fields.

How are quoted fields handled?

The parser correctly handles double-quoted fields, including commas and newlines inside quotes. Escaped quotes ("") within quoted fields are also supported.

Will numbers be converted to numeric types?

Currently all values are kept as strings to avoid data loss (e.g., leading zeros in IDs). You can parse numeric fields in your own code after conversion.

Can I convert TSV (tab-separated) data?

This tool is designed for comma-separated values. For TSV data, you can find-and-replace tabs with commas first, or use our YAML/JSON converter for other structured formats.

Is my data sent to a server?

No. All parsing runs entirely in your browser. Your CSV data never leaves your device.
