Excel file with Chart Sheet as first sheet - Exception

Hello all!

I have an Excel file in which the first sheet of the Excel file is Chart Sheet. This special sheet does not contain rows, columns, or cells, just a chart, like this:

When trying to get the range from the associated table on the second sheet (named “Dados”), UiPath returns an Exception:

After many attempts to understand why this happens, I have discovered that if the first sheet of the Excel file is a Chart Sheet (with no columns, no rows, no cells) UIPath gives the error.
If I change the file, and move the Chart Sheet to be second in order, then UIPath can execute the “Get Table Range” activity with no errors. So the problem here is when the first sheet is a special chart.

Does everybody has the same error behaviour?
(I am wondering if this is an issue of UIPath or my old Excel 2007).
If so, is it possible to change the order of the sheets in the Excel file?

I am attaching the Workflow and Excel file for you to simulate it.

I don’t get the error if I don’t use the application scope and when first sheet is a special chart.(not sure if it is programatically correct)


Hi @Thiago

Actually you are getting this error because your cast is wrong because you are using “Excel Activity Scope” with it.

Namespace: Microsoft.Office.Interop.Excel
Assembly: Microsoft.Office.Interop.Excel (in microsoft.office.interop.excel.dll)

This interface only gives you worksheets - not charts.

Go to Remark section :slight_smile:

On the other hand, if you will use “Workbook Activities” so it’s instance _Workbook.Sheets gives you a Sheets instance.

Go to Remark section :slight_smile:

The interfaces are not assignable to each other; therefore, you are getting the COM error.

i have not yet tried so do not know it’s possible to get an instance of the Worksheets interface through the “Office Primary Interop Assemblies”.

As long as you will use workbook activities i.e. _Workbook.Worksheets property instead of the _Workbook.Sheets property, you should get an instance of Sheets that only returns Worksheet objects for these charts objects etc. as i explained above.

Thanks @vvaidya and @aksh1yadav!

Using the Workbook Activites (without application scope) solves the problem. :clap:
