Excel Append Range - Exception from HRESULT: 0x800A03EC at Source: UiPath.Excel.Activities

Hi Forum,

I have a workflow to open an Excel file and append values to the specific sheet. But I got an error “Exception from HRESULT: 0x800A03EC at Source: UiPath.Excel.Activities” and the log stopped before the Append Range activity like in the picture below. Please help me solve this problem.

HI @wahid_rochman

Make sure you are using the latest version of the UiPath.Excel.Activities package. Outdated packages might have bugs that have been fixed in newer versions.


Are there any solutions besides updating to a newer version? Because this robot is already in production. And if I do the update there will be many more things to do because of the robot environment.

Hi @wahid_rochman

Did it stopped at the excel process scope container or else at the append range activity?


Use workbook append range activity instead of excel application append range

It stopped at append range activity. Right after log activity.

Hey, I tried your activity. however, it threw another error :

“ Job stopped with an unexpected exit

code: 0xE0434352

RemoteException wrapping

System.Exception: Job stopped with

an unexpected exit code: 0xE0434352”

can you check the size of the file or check if the file is corrupted, check the parameters you are passing are correct or not

Thanks for your help.

After adding kill Excel with reading all running Excel processes. this issue was done. I think this error appeared because there are several Excel processes in the background. But killing it with activity kill once wasn’t enough. So I added a loop read Excel processes and killed it.
