What Filee does for XLSX → PDF
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.
- Built in: works right after installing Filee, with nothing else to download.
- No Microsoft Office or LibreOffice needed.
- The merge preset combines all dropped files into one PDF.
- Text that needs shaping (Arabic, Hebrew, Indic scripts, Thai and others) is the exception: DOCX, TXT, Markdown, HTML, XLSX, PPTX and HWPX files with it go to PDF and images through the optional LibreOffice engine. Without LibreOffice, that file fails with a message naming the script instead of becoming a broken PDF.
- Batch: one file or hundreds, converted in parallel; a failure never stops the rest.
- Private: files are converted on your PC and never uploaded, even without internet.
- Saved next to the original, or in a folder and with a file name pattern you choose.

About XLSX and PDF
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.
