Open from Tableau Server tool is truncating long strings, and we don't have any control

[mk_chaitanya125]

I'm using Open From Tableau Server tool to read data from Tableau Server and republishing to Tableau after some processing - updating the data/adding new data. 

Our data has "description" field, which is often long - at least 10000 characters and the tool is truncating long strings automatically, which is causing loss of data. We don't have any control over the tool configuration. Can you please fix the macro and set it to the Tableau's default?
