Data exported from Excel or Google Sheets needs to become JSON for app seed data, a config file, or API test input.
Developers turn a plain spreadsheet into a ready-to-use array of objects, skipping a hand-written parser.
Frequently asked questions
Does the first row need to hold column names?+–
Yes. The first CSV row becomes the header and supplies the keys in the JSON output.
What about a comma inside a cell?+–
Wrap that cell in double quotes, like "text, with a comma". This is standard CSV format and the tool supports it.
Are data types like numbers detected automatically?+–
No. Every value becomes text in the JSON output, since CSV itself carries no type information.
Is my data uploaded to a server?+–
No. The conversion runs in your browser from start to finish.
