XLSX
Excel workbook
XLSX is the Microsoft Excel workbook format since Excel 2007. One workbook can hold several sheets with formulas, formatting, charts and pictures.
Extensions: .xlsx
Convert XLSX files to PDF on Windows 10 and 11: free, offline and in batches. Drag the files onto PDF in Filee's format donut and the PDF files appear next to the originals.
In File Explorer or on the desktop, select one XLSX file or as many as you like.
Hold Ctrl (or the key you set in Filee) and drag the files. A donut of formats opens at the cursor. Prefer menus? Right-click and choose Convert with Filee.
Release the files over PDF. A progress ring counts up, and each PDF file is saved next to its original.
Each visible sheet becomes its own section, with number formats, fonts, fills, borders and merged cells as Excel shows them. Wide sheets are scaled to the page width like Excel's "Fit all columns on one page", and frozen header rows repeat on every page.

PDF document
PDF is the standard for sharing documents that must look the same everywhere: fonts, layout and images are fixed and it opens on any device. That also makes PDFs hard to edit.
