Combine Data
Sometimes your data is splitted into several files and you want to work with all of them. It is possible in Statistiku to combine your data easily. Statistiku can merge CSV or Excel files.
You need to open your files one by one in order to tell Statistiku the sequence of your data. If you open a CSV or Excel file when the spreadsheet is not empty, you will get a confirmation dialog that ask you whether you want to overwrite the data or combine the data.

There are two ways to combine your data: insert it before your previous data or after your previous data. If you want the new data placed before your previous data choose Insert above option, otherwise choose Insert below option.
The Overwrite the data option will clear your previous data and replace it with a new one. You cannot undo this action.
