Activity Name: Read Range - Error: Your stream was neither an OLE2 stream, nor an OOXML stream

Hi All,

I am using Read Range to merge data table when suddenly bump into this error.


Kindly note that the files I am merging are .xls file. Can’t convert them to .xlsx because the file will not open under that extension.

Hy @caduque,

Could you share your files so I can take a look?


Unfortunately, I can’t. It contain a lot of confidential stuff.

Hy @caduque,

Create a copy of the files and mess up the data, something like that, could you try?
