CSV to JSON Converter
Turn pasted CSV text into an array of JSON objects.
The CSV to JSON Converter does the reverse job: it takes pasted CSV text and turns each row into a JSON object, using the first row as the key names. This is the go-to move when you have a spreadsheet export and need structured data for a script, an API, or a database import. It handles quoted fields and embedded commas correctly, so values that look like they would break parsing stay intact. If a row has more or fewer columns than the header, the extra or missing values are still captured so nothing is silently dropped. This is the return trip: a spreadsheet export goes in and structured records come out. The first row becomes the key names and every later row becomes one object, which is the shape an API request body, a seed script, or a database loader expects. Quoted fields and embedded commas are parsed correctly, so a value that looks like it would break the row boundary stays intact, and a row with the wrong number of columns still contributes what it has instead of being silently dropped. In practice you reach for it when a business team maintains a list in a spreadsheet and a service needs that same list as data, because the round trip through CSV keeps the source of truth somewhere non technical people can edit. It is also the fastest way to turn a one off export into a fixture you can commit to a test suite, and the flat one object per row output means you can feed the result straight into a loader without reshaping it first.

Frequently Asked Questions
How are rows mapped?
The header row becomes keys; each subsequent row becomes an object. Quoted fields and embedded commas are handled.
What if a row has extra columns?
Extra values are still captured; missing ones become empty strings. Validate your header before relying on the output.
Is my data uploaded?
No. Parsing happens locally in your browser.
