What it does

A free CSV to JSON converter that runs entirely in your browser. Paste CSV, pick the delimiter (comma, semicolon, tab, or pipe), and get a JSON array of objects — with the first row as keys by default. Handles quoted fields with embedded commas, escaped quotes, and both Unix and Windows line endings.

CSV is the universal data language everyone exports but no one enjoys parsing. JSON is what every API speaks. Going between them is a constant chore — this tool makes it a paste-and-copy in three seconds. For the opposite direction, see our JSON to CSV converter.

How to use it

Paste your CSV into the input box.
Pick the delimiter if it's not a comma.
Toggle 'First row is header' if your CSV doesn't have one.
Copy the JSON output or paste it straight into your code.
