Thanks for the sample project with template files.
After an initial test, I observed the issue as you mentioned by importing the two XLSM files (“BUDGET RH 3_0.xlsm” or “BUDGET RH 3_1.xlsm” in the folder “\AsposeGridWebTest\workbook” after extrating the project) into GridWeb. I found an exception: “Specified argument was out of the range of valid values. Parameter name: index” when importing XLSM files into GridWeb.
e.g Sample code:
GridWeb1.ImportExcelFile(savePath);
