JSON keys are destination headers; values are source headers. Output follows mapping order. Add files and review settings. Create the result, check the preview, actual size and limitations, then download a new file.
Practical example
Map an incoming table to another system's headers and order by defining destination-to-source names.
Scope and limitations
JSON keys are destination headers; values are source headers. Output follows mapping order.
Files are not uploaded to a server. Outputs are new files, so originals remain unchanged. Review the result before saving.
