If you have missing data, sorting it won’t line up all the rows correctly. But Data Mapper will. Where there is no data available (null), there will be an empty row.
Once you know the steps, it will take just a few seconds to use and will save you time.
There is no need for a manual. The software will guide you through the steps.
I takes me 10 seconds or less to use this tool, provided there are no problems to correct in the data, such as duplicate key values.
