I have resaved the workbook (.xls → .xls) with Aspose.Cells and the result is opened in Protected View by MS Excel. The original workbook opens without any warnings.
I attached the workbook.
Code sample:
var wb = new Workbook(inputFile);
wb.Save(“workbook.xls”);
I use Aspose.Cells.dll 25.3.0.0 and Microsoft® Excel® for Microsoft 365 MSO (Version 2501 Build 16.0.18429.20132) 64-bit.

A table was applied in A7:A8, but the name of the table column is not same the value of the Cell A7. If you open and resave the file with MS Excel(2007 - 365), open it again, you will find an error was popped up. In order to avoid such error, we have to sync the value of the cell to the name of table column when saving the file. But the max length of column’s name is 255,so the saved xls file is in protected view.
Please check why there is such a table in “A7:A8”.
We plan to keep the old table column’s name when saving xls file.
