Free CSV to JSON Converter

CSV (Comma-Separated Values) is the most common format for exporting data from spreadsheets and databases. Our converter uses the industry-standard PapaParse library to parse your CSV with RFC 4180 compliance, handling quoted fields, special characters, and large files with ease. Headers are automatically detected and used as JSON keys. Everything processes locally in your browser.

Features

  • Auto Header Detection: First row becomes JSON keys automatically
  • Dynamic Typing: Numbers and booleans are automatically detected

Privacy

  • 100% Client-Side: Your data never leaves your device
