How to finish your task

XLSX output uses text cells. Already lost zeros or truncated IDs cannot be recovered. Add files and review settings. Create the result, check the preview, actual size and limitations, then download a new file.

Files are not uploaded to a server. Outputs are new files, so originals remain unchanged. Review the result before saving.
