CSV ↔ JSON

Convert between CSV and JSON formats. Supports custom delimiters, header detection, and quoted fields.

What is CSV?

CSV (Comma-Separated Values) is one of the oldest and most widely used data exchange formats. Each line represents a row, and values within a row are separated by commas (or other delimiters like semicolons or tabs). CSV files are used for spreadsheet exports, database imports, data analysis, and interoperability between systems. Converting CSV to JSON makes tabular data accessible to web applications, APIs, and JavaScript-based tools.

How to Convert CSV to JSON

1

Paste your CSV data into the input panel. The tool auto-detects common delimiters (comma, semicolon, tab).

2

Toggle "First row is header" to use column headers as JSON keys. Choose your delimiter if auto-detection doesn't match.

3

View the converted JSON output instantly. Each CSV row becomes a JSON object with keys from the header row.
