Your spreadsheet export, on a server
- Uploads rows that may hold customer data
- Guesses at headers and delimiters silently
- Caps rows on the free tier
Headers become keys
- The header row becomes keys; each row becomes an object
- Semicolon and tab delimiters handled where detected
- Runs in your browser with no upload
Questions worth answering upfront.
No. Conversion happens entirely in your browser. Your data is never uploaded or stored.
Yes. The header row is treated as the object keys, and each subsequent row becomes a JSON object.
Comma, semicolon, tab and pipe. The delimiter is detected from the header row automatically, and delimiters inside quoted fields are left alone.
Yes. Every tool on DevUtilsNow is free to use with no account required.
In Python: rows = list(csv.DictReader(open('data.csv'))), then json.dumps(rows, indent=2). In JavaScript, a parser such as Papa Parse with header: true returns the same array of objects. For a single file, pasting it here is quicker.
