Read Range Error for only some excel files...?


I’m building a bot right now that uses the “read range” activity for a datatable in excel. It is working from some excel files but not others. See below for the error. Could someone read this and let me know what is causing this error? Thank you!

Source: Read Range

Message: Index was outside the bounds of the array.

Exception Type: System.IndexOutOfRangeException

An ExceptionDetail, likely created by IncludeExceptionDetailInFaults=true, whose value is:
System.IndexOutOfRangeException: Index was outside the bounds of the array.

Can you share some sample excel which is throwing you error?

As per your posted error, The range is not correct, can you check that


@Srini84 I was able to clean up the data and now I have 2 excel files, one that works when I run it and one that does not. I’ve also attached the UiPath file as well so you could take a look at that.

I’m failing at the step inside “copies each new picture” sequence at the first read range activity.

Would greatly appreciate any help here.

@Srini84 Hey! Were you able to look into this at all? If not that’s ok too!



As i didn’t see any reply from you since long time, so i thought the issue was closed, Any way, the flow is asking for some ppt file, so can you share me that file too, so that i can check and get back to you


@Srini84 here is a ppt file that I just tested the bot on my end and it does work with the “working file” that I have provide above. Thank you so much for the help!
