If anyone has found any solution for this error, Please share in it comments.
I want to use only workbook read range.



Could you please help me with screenshots of that workbook read range Activity and it’s properties once. Will check and update you.


It’s looks ok. How many no. of rows that Excel file has ?

I guess it’s contains many no. of rows and because of that you are getting this error. Could you please specify some range and once try it.

Hi @praveen_satya

Try to give the range as “A1: A+datatable.rows.count.ToString+”


Welcome to uipath community
Kindly uninstall the EXCEL package in the Design Tab → Manage Packages → Project dependencies ->uninstall the excel package and again reinstall by going to Official tab → search for Excel.Activities and install it
–use a read range activity and mention the range as “” no space in between and the sheetname and workbook path same as how its mentioned now

Kindly try this and let know for any queries or clarfication
Cheers @praveen_satya

Hi all,

Ashwini - I could not able to read the data to get datatable. I have given the exact range as well still the same error.

Lakshman- I believe Rows count is not a problem here, i am getting the same error for files with data of 10000 rows and 10 rows as well.

Hi Palaniyappan,

I did the same still the same issue.

I can read the same file with Excel Application Scope Read range but problem here is when i run in VDI, bot is in reading mode for hours (Ex: 10 hrs) and It is not even throwing any error after 10 hrs.
So that’s why i want to read data using Workbook Read Range.

I have even tried to read excel file as database. I could able to get datatable but that is returning me null values.

HI Praveen

Are u getting the same error irrespective of the files u r reading ?
can you make the range as blank and try

Hi Vishnu

I couldn’t able to read the reports which i have downloaded from SAP. Normal Excel files i could able to read with workbook Read Range.

Range Property - I have tried with all possible ways with blank(“”),given the exact range and taken dynamically as well. No Luck same error.

I couldn’t figure out what could be the error. Error message shows Index out of Range Exception.

Hi Guys,

I found a solution by copying the data from downloaded Report to a new Workbook using VB script and then Reading that new Workbook file. It is working like that.

May be Data got corrupted when it got downloaded from SAP.
