The data can be brought into QlikView in a number of ways with a Load Script.
To be able to give you sound advice you need to tell us how you really need the data to be in the QVD or CSV format file(s). Can you leave it exactly like it is in Excel or do you need to transform it in any way?
1) It could be read as is - which means that the structure of the data is unchanged from this report oriented format. This is rather unpractical if you want to do some analysis or further enrichment of the data from other sources.
2) You can restructure the data as it is read in the load script so it turns into a more optimal format for analysis and building an application.
Then the most convenient way is to change the month columns into rows by using a CROSSTABLE LOAD to
"unpivot" the columns into more rows.
Since these are multiple tables using multiple CROSSTABLE LOAD statements would be necessary to get all of the data in correctly.
You can use the LOAD SCRIPT editor and the Table Files wizard to bring in the data this way.
3) You can use one or more STORE statements at the end of the load script to produce either CSV-files or QVD-files.
