Hello All ,
Whenever I use any workbook activity like read range , read column , etc. I am getting error as “Index was out of range. Must be non-negative and less than the size of the collection.Parameter name: index”.
But , When I used Read range with exact same range parameters within Excel application scope , its working.
Can anybody please help.
Regards,
Akanksha
Welcome to our UiPath community.
Could you please help me with screenshot of Workbook Read Range activity. Need to check once how you are passing data to it.
receiptColumn is the output of Read Column activity .
If I use same parameters (sheetname , filename , range) within excel application scope. It works
I am attaching one workflow which can help you to get the difference between the Excel & Workbook activities Cell Range Property.
Just run/debug the workflow.
IncreamentMonthAsPerSerialNo.xlsx (8.8 KB)
Main.xaml (12.8 KB)
Actually Datatable value starts from 0.
And Normal Row index starts from 1.
Hope this may help to solve your issue

Thank you. I have tried copying the data which I need to read in some sample excel. I kept the range same. There it worked. As per my observation , this activity of workbook (Read range , read column , write range) is not working if the excel contains pivots n all. In the regular excel (without pivots) its working on the same data.
I am not sure if my observation is correct.
Hello, did you find any solution for this? I am facing the same issue and yes my excel file also has Pivot table
Hi @Pratik_Wavhal &/or anyone,
I’m a new to UiPath & I began with the “Get Started With RPA Development” course. In the 1st video tutorial I encounter the "Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index.
Please see the attached screenshot. I am using the MailMessages(0) index as indicated in the tutorial. Any assistance, will be greatly appreciated.
Thanks,
Hector
Hey! How did you solve this issue? Thanks

I had the same issue. Did you figure it out? Want to move onto next tutorial, but don’t think it would be wise if I cannot figure this first issue out.
Hey did you ever figure this out? I had the same issue.
Hey did you ever get this figured out?
Not Yet, if you find something please let me know, as a work around im creating another file without pivots.
Apologies for not being available to respond earlier.
E.g., when creating a variable, the type is automatically generated depending on the selected property and this directly affects the scope. As a result, I found the managing variables link to be very helpful.
Thank you for your response. I will try to work it out.
Check Hector’s response. He just added some info that might be helpful.
Please see my response in the UiPath Forum.
