What format should my CSV be in?
The first line of your CSV must be a header row containing column names. Subsequent lines should contain the data separated by commas.
Is my data safe?
Yes, all conversion happens directly in your browser. We don't store or transmit any of your data to our servers.
How to convert CSV to JSON
- Paste CSV with a header row on the first line.
- Each column header becomes a key; each row becomes one object.
- Copy the resulting array of JSON objects.
Frequently asked questions
Does the first row need to be a header?
Yes. The first line is treated as the field names that become the keys of every JSON object.
How are values typed?
Values are kept as strings to avoid surprises. Cast numbers or booleans afterward if your schema needs them.
