    Hi,

    can you share the flow?

    Sure! - there are a couple of booleans.... but you can ignore the ifs part.

    Thanks!

    A quick google search indicates that the error can be related to several things in Excel: "The error code 

    0x800A03EC (or -2146827284) means NAME_NOT_FOUND; in other words, you've asked for something, and Excel can't find it."

     

    Could it be that what you are trying to write to Excel does not conform to the size or format of the sheet? I see that you populate the DownloadedFiles-variable with other variables - this might be part of the issue? Could be that the list is longer than what fits into the sheet or the format isn't accepted?

    Hi,

    I'd suggest changing the row from 0 to 1, for the "Write to Excel worksheet" action.

    Really the comment in this case belong to a "missed Drive letter"; so the explaination provided is fine, obviouly with the Monday Newspaper.
