📘 About the CSV to JSON
Paste CSV — or copy cells straight from Excel or Google Sheets, which pastes as tab-separated text — and get a JSON array of objects. The first row supplies the keys.
Quoted values with commas or line breaks inside are handled correctly, and numbers and true/false can be turned into real JSON values.
💡 How to use the CSV to JSON
Paste CSV or cells copied from a spreadsheet.
Leave the separator on "Detect automatically" or choose one.
Click Convert and copy the JSON.
❓ Frequently asked questions
Will numbers with leading zeros be kept?
Yes. Values such as 0123 or long ID numbers stay as text so no digits are lost.
