Compare how tested applications handle .XLSX files. Opening support does not always mean that every part of the file remains fully editable.
What does .XLSX compatibility mean?
Excel Workbook files can behave differently depending on the application used to open them. A program may display the file correctly while changing its internal structure, editable elements or visual fidelity.
We distinguish direct support from limited workflows and formats that are not natively accepted.
A file that opens successfully may still lose editable text, vectors, layers or other source structure.
Individual reports examine properties such as layers, fonts, transparency and output quality when relevant.
