Want to include your text?
Your current input will be stored in the link after the # symbol, not uploaded to HandyBrowserTools. Anyone with this link can read that text. If you send or post it, the service you choose also receives the link. Do not include passwords or private information.
Frequently asked questions
Does the first row have to be a header?
Yes, the first row is used as the JSON object keys. Empty header cells become column_1, column_2, and so on.
Are quoted fields with commas supported?
Yes. Standard CSV quoting is fully supported: "New York, NY" stays one field, and doubled quotes ("") become a literal quote.
Is there a file size limit?
No hard limit. Processing is local, so it depends only on your browser's memory.
