The file loaded without error, contrary to the stated limitations:
Free version is limited to 5 sheets per workbook and 200 rows per sheet. This limitation is enforced during reading or writing XLS or PDF files. From Free Spire.XLS v7.8, there is no any limitation when loading and saving .xlsx file format
I'm assuming the statement "From Free Spire.XLS v7.8, there is no any limitation when loading and saving .xlsx file format"
also applies to .xls file [/b]format"?
