About the CSV to JSON Converter
This tool reads CSV (comma-separated values) — the format spreadsheets export — and turns it into a JSON array of objects, using the first row as the keys. It understands quoted fields that contain commas. The conversion happens entirely in your browser, so your data stays private.
