CSV ↔ JSON: Moving Tabular Data Around
CSV is tabular (comma-separated); JSON is structured. Converting an Excel-exported CSV to JSON lets you feed an API; converting API JSON back to CSV makes it readable in a spreadsheet.
Conversion points
- Fields containing commas must be wrapped in quotes
- Specify a custom delimiter (e.g., semicolon) when needed
- JSON arrays to CSV auto-generate headers
Typical flow
Excel → Save as CSV → convert to JSON → call API; or API JSON → convert to CSV → analyze in Excel.
💡 FreeToolset's CSV/JSON converters handle quoted fields correctly and stay smooth even with large files.
