Frequently asked questions

Are quoted CSV fields supported?+

Basic quoted fields and commas inside quotes are handled for common CSV exports.

How do I convert a spreadsheet export to JSON for an API?+

Export CSV, paste it into ToolVera’s CSV ↔ JSON converter, and copy the JSON array of objects. Conversion runs locally so sensitive rows are not uploaded.

What if my CSV headers have spaces or special characters?+

Header names become JSON keys as written. Rename columns in the sheet first if you need camelCase keys or to avoid awkward property names in code.
