How XLS turns into PDF: Workbook object-model rebuilding
Reading XLS means pulling cells, sheets, formulas, types, and print settings, then mapping all of it into whatever structures PDF can actually express. A total that still displays correctly is not proof; formulas and leading zeros can shift underneath it. XLS uses a legacy binary workbook stream whose formulas, shared strings, formats, sheets, charts, and date system must be interpreted before export. Composing fixed pages from text, vectors, and images is what PDF output does; searchable text, fonts, links, forms, tags, page boxes, and print rendering all still need checking separately.
Read structure - The legacy binary Excel workbook with cells, formulas, formats, and older size limits. Rebuilt structure - Fixed pages containing text, vectors, raster images, links, forms, and other document objects.

Acceptance evidence for the converted PDF
Record the XLS evidence before conversion
Recalculate in the target Excel version and inspect formulas, dates, named ranges, charts, and sheet count.
Test the PDF file in its receiving workflow
Review every page size plus searchable text, links, forms, fonts, and print output.
XLS source facts versus PDF output requirements
What can fail when XLS spreadsheet format is interpreted
Newer functions, long worksheets, charts, macros, and date systems may not fit the XLS model.
What Portable Document Format cannot safely promise
Conversion can rasterize searchable text, alter page boxes, omit forms, or change font rendering.
How the PDF writer handles this route
fixed pages containing text, vectors, raster images, links, forms, and other document objects is what gets written, labeled as application/pdf. Whether that actually opens depends on the receiving application, not on the file extension.
Deciding when XLS to PDF is the right conversion
PDF earns its place when its editing, reflow, or reader support outweighs exact XLS structure - Just test the most complex page or chapter before committing to it.
What changes between the XLS model and the PDF deliverable
- LibreOffice lays out the pages, so fonts that are not installed on the server are replaced with similar ones; check line breaks and page count.
- XLS and PDF use different metadata conventions, so application-specific fields should be treated as optional until verified.
