Frequently Asked Questions

Does the converter handle quoted fields with commas inside them?
Yes. The parser correctly handles RFC 4180-compliant CSV, including quoted fields that contain commas, newlines, or escaped double quotes.
What delimiters are supported?
The tool supports comma (,), semicolon (;), pipe (|), and tab as delimiters, covering the vast majority of CSV and DSV file formats encountered in practice.
Is my CSV data sent to a server?
No. All parsing and conversion happens in your browser. Your data never leaves your device, making it safe for sensitive or confidential spreadsheet data.

About CSV to JSON

The CSV to JSON Converter on Utilko is an indispensable tool for developers, data analysts, and anyone who works with tabular data. CSV is the universal export format for spreadsheets, databases, and reporting tools, but many APIs and modern applications expect JSON. This tool bridges that gap in seconds.

The converter intelligently maps each CSV column header to a JSON object key, producing a clean array of objects that can be immediately used in JavaScript, Python, or any JSON-consuming application. Support for multiple delimiters means it works with European semicolon-separated files and tab-separated formats just as well as standard commas.
