Meet a problem when using gHowl to read spreadsheet

[Xinquan (Wenxinquansh)]

Hello!

I tried to use gHowl to read data from Excel.
Have followed this amazing answer by Danny.
installed the OpenXMLSDKv2.msi file and gHowl_r50

The red spreadsheet reader says 1. Solution exception: System.NullReferenceException

Could anyone help me with this?

Cheers,
Xin

probably needs .xls format, or the file is open and it can’t read it.

This excel reader works well…

Import and export Excel files with the NPOI plugin : EXCELLENT!

This Plugin rocks ! NPOI_Excel Plugin -No need for Excel to be opened -Very fast write -Ability to create files with multiple worksheets -Import and export of cell ranges -… It is based on NPOI, a Dot Net port of POI , a java library allowing to read and wrtite multiple Microsoft formats. The example file is partly in Chinese, but I have translated it in English here : ExcelExample-Translated.gh (17.8 KB)

Thank you so much : )
Excel reader works well!! It took me a while, I was careless about the spaces inside the file & sheet names.
By the way, it works with .xlsx
