This tool converts a CSV file into a JSON array of objects, using the header row as keys. Drop your CSV above. The JSON file downloads automatically once ready.
FAQ
Does my CSV need a header row?
Yes, the first row's values become the JSON object keys, and every following row becomes one object using those keys.
Does it handle commas inside quoted fields?
Yes, the parser follows standard CSV quoting rules, so a comma inside a quoted value is not treated as a column separator.
What happens to blank rows or blank cells?
Fully blank rows are skipped entirely. A blank cell in an otherwise filled row becomes an empty string in the resulting JSON, not a missing key.
Are numbers and booleans converted to their JSON types?
No, every value comes out of a CSV as text, and this tool keeps them as strings (e.g. "42" rather than 42) rather than guessing types. If your downstream tool needs real numbers, you'll need to convert them there.
