Does the validator upload my XLSForm?
No. The workbook is parsed and checked in your browser. SurveyLoopr does not receive the file, its filename, or its contents.

Check an XLSForm workbook
Upload an .xlsx file for a quick structural and logic check.
Your file stays in this browser and is not uploaded.
This is a SurveyLoopr quick check for workbook structure and common logic errors. It is not official ODK Validate or a substitute for testing the form in ODK Central and on a device.
Edit, preview, and export in SurveyLooprWhat this XLSForm check catches
The browser check reviews the workbook shape that commonly causes an ODK upload failure: a missing survey sheet, missing `type` or `name` columns, invalid field names, duplicate names, unknown question types, missing labels, and common expression syntax errors.
It is a fast first pass, not a certification. For a complete workflow, open the workbook in LooprAI to edit and review it, then validate and preview it in the workspace before downloading or publishing.
