Frequently Asked Questions

Everything you need to know about CSV to JSON conversion

Do I need to sign up or log in to use this tool?

No. All QuickTextTools are completely free to use online with no login, signup, or account required.

What delimiters does this tool support?

The tool supports comma (,), semicolon (;), and tab (\t) as delimiters — covering the most common CSV and TSV formats.

What happens if my CSV has a header row?

When 'Has Header Row' is enabled (default), the first row is used as JSON keys. Each subsequent row becomes an object with those keys. If disabled, rows are converted to arrays of values.

Does it handle quoted fields with commas inside?

Yes. The parser correctly handles RFC 4180 CSV format — fields wrapped in double quotes containing commas or line breaks are parsed accurately.

Is my CSV data sent to any server?

No. All conversion happens entirely in your browser using JavaScript. Your data never leaves your device.

What is the difference between pretty print and minified JSON?

Pretty print outputs JSON with indentation and line breaks for easy reading. Minified output removes all whitespace, producing a compact single-line JSON string ideal for production use.
