About CSV to JSON
Developers and many web tools want data as JSON. This converter reads your CSV, uses the first row as field names, and turns every other row into a JSON object.
Every value stays text, exactly as in your file, so postcodes, phone numbers and IDs keep their leading zeros. The separator (comma, semicolon or tab) is detected for you, and the file never leaves your device.
The result is an array of objects with one object per row, nicely indented so you can read it. Each field name comes from the matching heading in the first row. A cell left empty becomes an empty string.
Quoted values that contain commas or line breaks stay in one field. If you need numbers instead of text, change them in your code or in a JSON editor afterwards. Customer lists and order exports are often private, which is why the conversion happens on your own device.
