How to separate data coming in one column of CSV file?

I am running an ISQL command on Sybase DB and getting output of a query in an CSV file.

The issue is that all the data comes in to the same column, i want them to be separated in different columns.

SQL_COMMAND=command.sql
file=file.txt
formatFile=formatFile.txt
report=report.csv

echo "SELECT  'DATA',usr_nme,'          ',office'  ',frst_nme,'         ',last_nme
        FROM    abcTable" > $SQL_COMMAND
isql -U ${USER} -S ${SERVER} -P ${PW} -i${SQL_COMMAND} -w300 -o ${file}
            
grep DATA $file >> $formatFile
sed s/DATA// $formatFile >> $report

All the four columns data, i.e user name, office first name and last name comes in single column of csv file. Please suggest how can i separate it.

Sample of output:

  sharma331 	 0116               	 Alisa                                	 kri

Above data comes in single column
