CSV to JSON Documentation

Parse CSV data into structured JSON arrays and objects for quick app, API, and spreadsheet workflows.

Paste CSV or select a local file up to 5 MB. Detect or choose the delimiter and header handling. A quote-aware parser preserves spaces, escaped quotes, and multiline cells. Values stay strings unless type detection is enabled.

• Convert a spreadsheet export while keeping leading zeroes as strings.
• Read quoted multiline cells without splitting them into separate records.

Input

Text, files, or values entered in the browser, depending on the tool.

Output

A result shown in the browser that can be reviewed or copied where supported.

• Values stay strings by default; optional type detection can convert numbers and booleans.
• Pasted text is limited to 5,000,000 characters and file selection to 5 MB. With a header row enabled, headers must be unique and non-empty.

Inputs for this browser-side tool are processed locally and are not sent to SiteIndex. Normal page analytics may still be collected as described in the Privacy Policy. Read the Privacy Policy.
