I’m using DotNetCore.NPOI v1.2.3 in C# to read an existing Excel document. My stackoverflow tag says “npoi”, an appropriate tag doesn’t seem to exist, and I’m unable to create one.

I am using NPOI to build a workbook with multiple worksheets. It does the first sheet just fine and adds the second sheet but does not write the data to it. When I put in a breakpoint and step through the code it appears to be adding the data but when I open the spreadsheet the second sheet is empty.
