    2. Review the settings and create your result.
    3. Download and check the output before using it.

    Output and limitations

    Convert CSV rows into JSON objects while preserving text values.

    The first row must contain unique, nonempty column names. Quoted commas and multiline cells are supported. Values stay strings so leading zeros are preserved.

    What if processing fails?

    Check the supported formats and file limits, then try a smaller file. Keep an original copy. A clear error message will explain an unsupported input or an unavailable processing service.
