XLS output creating apostrophes at the beginning of string columns

[gdefazio]

Hi all,

I am converting a cvs file to an xls within my workflow, and it is returning columns with ' before strings only. When I attempt to run the file back through Alteryx, it does not show the apostrophes before the strings and only shows when I open the excel file. The output looks normal when in a regular xlsx file. 

Example: 

xlsx output: 4R47223
xls output: '4R47223

I'd recommend outputting to .xlsx - .xls is a legacy file type that will no longer be supported going forward! Whatever system needs it as .xls, I would push back and see if you can do .xlsx
