I converted records list into excel using Record List to excel. I want to add this sheet in to a new workbook.  I tried to add sheet using Workbook_AddSheet action of Advanced excel forge component. But I got the error as object reference not set to an instance of an object.  Attached screenshot for reference.
How to resolve this issue ? Any other alternative to add sheet ? Thanks in advanced!

Advanced Excel error while adding new sheet.png

Hi @Sharad Pawar

Record List to Excel is a built-in action that already creates the excel file, you just need to download it after on your screen / client action.
See a detailed explanation here for both reactive and traditional web:

To use advanced excel you should use the component actions to write to the worksheets and then add them to a workbook that you can later download. You probably don't need to use this component if you don't require complex excel manipulation.

Hope it helps, cheers


From screenshots its clear that you are getting error in WorkBook_AddSheet method.

Do you tried to add worksheet at the time of workbook creation in Workbook_create method.

Instead of using WorkBook_AddSheet method you can create first worksheet using below method: Just need to pass first sheet name.
