One PDF from every tab you actually print
Excel’s native export is tedious on a 12-tab monthly pack. This spoke is that automation: one upload, sequential pages. It is not a custom “include sheet 3 and 7 only” picker — hide or delete tabs you do not want before you upload, or split after with Organize PDF.
Active sheets vs hidden
LibreOffice renders the sheets it sees as part of the print workbook. Hidden tabs are often omitted; very-hidden VBA sheets can surprise you. Unhide everything you need, hide everything you do not, save, then convert.
Order and orientation
Sheet order in Excel is page order in the PDF. Drag tabs in the workbook first. One orientation applies to the whole convert — export odd layouts separately if a cover must stay portrait and a data tab must stay landscape.
After the combined file
Rotate or delete a leftover blank with Organize Instant (local). Compress if mail rejects the pack. Multi-workbook folders are Premium batch, not this single-file flow.
