CSV to JSON Converter
Paste your CSV below, or drop a file. The first row is treated as column headers. Conversion happens locally — nothing is uploaded.
Spreadsheet exports rarely arrive in the shape an API or script expects. This tool exists for the moment you've got a CSV from Excel, Google Sheets, or a database export and need it as structured JSON to feed into code, a config file, or a no-code tool that only accepts JSON.

Common questions
Does this upload my CSV file anywhere?
No. The conversion runs entirely in your browser using JavaScript. Your file never leaves your device.
Is there a file size limit?
No artificial limit is imposed by this tool. Very large files are limited only by your browser's available memory.
Does it handle commas and quotes inside CSV fields?
Yes. Fields wrapped in double quotes can safely contain commas, line breaks, and escaped quotes ("").
