Upload and analyze a workbook
The Excel compatibility check runs immediately and blocks unsupported files before remark generation begins.
Upload a Massar Excel workbook
Drag and drop the exported `.xlsx` file here. The workspace validates workbook structure before any remark is generated.
The export flow edits the original workbook instead of rebuilding it.
Header rows, student range, and Massar column mapping are checked automatically.
Bulk upload stays locked until the paid plan is activated
Free users can use single exports first. Bank transfer or card payment requests can be collected from the upgrade panel above, then the subscriber plan unlocks this batch workflow.
Upload multiple workbooks and export them in one batch
Teachers can queue up to 10 Massar `.xlsx` files, generate remarks in one click, then download everything as a ZIP archive or grab individual files.
