I have an SAP export to .xls file that formats number with “,” as decimal separator and “.” for thousands. When I open the .xls file manually with excel the formats are correct, but when I use the “Use Excel File” activity it messes up the formatting and transforms “.” into “,”.
Update
I found a solution by opening the .xls file using “start process” activity (which simulates a “manual open”) and then saving the file as .xlsx
When later in the process I open the .xlsx file using the “Use Excel File activity” it works fine and does not mess up the separators.
