CSV is the lingua franca of spreadsheets and exports, while JSON is what APIs and apps consume. Converting between them by hand — especially with quoted fields containing commas — is error-prone. This free CSV ⇄ JSON converter parses robustly and converts both directions instantly in your browser.

How to convert

Pick CSV → JSON or JSON → CSV.
Paste your data; for CSV choose whether the first row is a header.
Copy the converted result.

Why use this tool

Robust CSV parsing (quotes, commas, newlines).
Header-row toggle for objects vs. arrays.
Runs in your browser — private and free.

FAQ

Does it handle quoted fields?

Yes — quoted values with commas, line breaks or escaped quotes ("") are parsed correctly.

What does "First row is a header" do?

When on, the first CSV row becomes the object keys, producing an array of objects. When off, you get an array of arrays.

Is my data uploaded?

No. Parsing and conversion run entirely in your browser.
