However, XmlCursor in NPOI is not correctly implemented. https://github.com/nissl-lab/npoi/blob/649cf37074ca78210f6f118e598cab9ff6844254/ooxml/XWPF/Usermodel/IBody.cs#L110 InsertNewTbl should have a XmlCursor argument instead

Why do you think dx1 and dy1 is not working? Any clues?

As I remember, this issue has been fixed in NPOI official release. Please use nuget.org/packages/NPOI/ instead. xhelper 于2020年7月29日周三 下午3:07写道： > return File(memoryStream.GetBuffer(), "application/vnd.ms-excel", > "test.xlsx"); > 流关闭了再读取一次数据，使用另外一个重载方法返回； > > —...

The current version of NPOI doesn't support this since XWPFChart and XDDFChart have not been migrated from POI yet.

You can try SXSSFWorkbook. It did save some memory by using temp file on disk while unzipping the xlsx. But frankly speaking, Excel doesn't support streaming read by default.

I don't use Unity. Maybe someone else can help.
