Five real reasons to convert CSV to JSON

  1. Compatibility — the recipient's software opens JSON but not CSV.
  2. Size — JSON compresses better for most modern web use cases.
  3. Quality controls — JSON gives you finer-grained settings that CSV doesn't expose.
  4. Platform requirements — uploaders that demand a specific format leave you no choice.
  5. Workflow consistency — standardising on one format across a batch is easier to maintain.
