Convert CSV to formatted JSON
Turn a CSV into an array of objects, then pretty-print the JSON.
Convert comma-separated data into clean, indented JSON in two steps: parse the CSV into an array of objects keyed by the header row, then format the JSON with proper indentation so it is readable and diff-friendly.
This is the fastest way to get a spreadsheet export into the shape an API or a config file expects, without pasting sensitive rows into an online converter — the whole conversion happens locally in your browser. Paste your CSV below to see the formatted JSON.
Questions
Does the first row become the keys?
Yes. The CSV parser treats the first row as the header and uses those names as the keys of each object.
Can I change the indentation?
Open the formatting step on its own tool page to pick 2 spaces, 4 spaces or tabs. The recipe uses the default pretty-print.
Is my data sent anywhere?
No. Both steps run in your browser; the CSV never leaves your device.
