That's very good suggestions but i will have to calculate the .csv file with around 2000000 rows of data in order to compare against another excel . I will not have any server to install database. Can i create a temporary .db file in my system and save the data and then fetched the data as .csv. How i can handle the .xlsx file's row limitations in case i will have 2000000 rows of records to handle? Can i create dynamic worksheets by checking the records in array?
