.NET Framework exception when reading excel file

Hi @priyatham,

Kindly check if the excel package was updated, probably it’s causing the problem and try to revert it to the previous version by copying it to the folder C:\Program Files (x86)\UiPath Studio\Packages.

Before copying the older version, be sure that UiPath is closed.

You may check it’s version here:


The package did not get updated, but there is an update to some Microsoft Office products. we think, this might be the reason.
