How it converts
- JSON → CSV: each object becomes a row. Nested objects become columns like
address.pin; arrays are kept as JSON text in one cell. Missing keys become empty cells. - CSV → JSON: the first row becomes the keys. Commas, quotes and line breaks inside quoted values are handled. Numbers like
007or phone numbers stay as text so leading zeros are kept. - The downloaded CSV opens correctly in Excel, including Hindi text and the ₹ sign.
Questions
My CSV uses semicolons. Will it work?
Yes. The delimiter is detected automatically (comma, semicolon, tab or pipe), or you can choose it.
How large a file can it convert?
Tens of thousands of rows work fine. Very large files may make the browser slow, since everything happens on your device.
Is my data uploaded?
No. Conversion runs in your browser.
