Hi ,
In the release Version 2019.2.0. I have added a new activity called Change Cell Type. It changes the format of the value like below.
In the Cell Format , can specify the custom format what we have in the excel Like below image.

Sample : UiPathGoExcel.zip (18.4 KB)
This is the video to configure the package in local.
Here is the link to know about the formats.
