Hallo everyone, can someone help me with this, i am trying to export list rfom Dynamo to Exel using Data.ExportExcel node, but i keep getting this warning: (Null value cannot be converted to Int32 ), what does it mean?. Thank you

@yazanhijazeen32 startCol has to be a number [0 for A, 1 for B and so on…) Also you might need to provide a sheetName. [image]

@yazanhijazeen32 Please share a screenshot of your graph. Make sure to pin all the output previews.

kindly show the Warning message in the snap and it seems that u have not provided the sheet name so it may be the problem usually, it is “Sheet1” for a new excel file or change the sheet name as in the exporting excel file try this out [image] [image]

@AmolShah thank you, it worked :ok_hand: :ok_hand:
