Guide
How to convert CSV to JSON
1
Paste or Upload CSV
Drop in your CSV text, or upload a .csv file. The JSON and a table preview appear right away.
2
Set Your Options
Pick the delimiter, say whether the first row is a header, and choose if numbers and booleans should be parsed instead of left as text.
3
Copy or Download
Switch between the JSON and table views, then copy the JSON or download it as a .json file.
From a Spreadsheet Export to Usable JSON
CSV is the format spreadsheets and exports hand you, but most code wants JSON. Converting by hand means splitting on commas and hoping none of the values contain commas of their own, which they often do. One quoted field with a comma inside and a naive split falls apart.
This converter reads CSV the proper way. It respects quoted fields, handles commas and line breaks inside values, and turns each row into a JSON object keyed by the header. You get a clean array of objects that drops straight into your code or an API call.
You decide how strict it is. Pick the delimiter your file uses, tell it whether the first row is a header, and choose whether to parse numbers and booleans into real types or keep them as text. Everything runs in the browser, so private exports never leave your device.

FAQ
Frequently Asked Questions
Common questions about converting CSV to JSON.
What does the output look like?
You get a JSON array of objects. Each CSV row becomes an object, and the header row becomes the keys. So a row with name and email columns turns into an object with name and email fields.
Does it handle commas inside values?
Yes. Fields wrapped in double quotes can contain commas, quotes, and line breaks, and the parser keeps them together as one value instead of breaking the row.
What does parsing numbers and booleans do?
With it on, a value like 42 becomes a real number, true and false become booleans, and null becomes a JSON null. With it off, every value stays a string. Leading-zero values like 007 are kept as text so they are not changed.
What if my CSV has no header row?
Turn off the header option and the columns are named column1, column2, and so on. Every row, including the first, is treated as data.
Can I use a different delimiter?
Yes. Choose comma, semicolon, tab, or pipe to match your file. This covers exports from spreadsheets that use a semicolon or tab instead of a comma.
Is this CSV to JSON converter free?
Yes, it is completely free with no signup and no limits. Everything runs in your browser, so your data stays on your device.
