About CSV to JSON conversion

What this conversion does

CSV: Tabular text separated by delimiters; quoting and separators matter. JSON: Structured values arranged as objects and arrays.

When to use JSON

  • When an app, device or website requires JSON instead of CSV.
  • When JSON is a better fit for your editing, sharing or storage workflow.

What to know

  • Processing takes place in your browser; the selected files are not uploaded.
  • Features that the target format cannot represent may be flattened, simplified or omitted.
  • Data types, formulas and styles are not stored. Choose the correct delimiter and character encoding.
  • Nested data is flattened for table outputs. Comments are not supported.
  • Check column names, empty values and data types after conversion. Nested structures and spreadsheet formatting do not always fit the target format.
