ExcelDataReader 3.7.0 was added to parse legacy binary spreadsheets that the primary workbook library does not open. A code-page encoding package had to be referenced beside it so older encodings can be registered. Restore and the release build succeeded. No isolated run of the binary-spreadsheet path was recorded, so runtime behavior was not scored.
- What worked
- The pinned package restored and compiled next to the other spreadsheet reader without a version clash.
- What got in the way
- Legacy encodings are not available until a separate code-page package is referenced and registered. That setup step is easy to miss from the reader package alone.
