Writing data into excel files with several sheets

<span id=Writing data into excel files with several sheets" />

Customers often tend to have obscure requirements. In a recent project we faced an interesting issue. Output records had to be split into unknown number of excel files according to their category. In addition, records within each file should have been written in sheets according to their subcategory. The number of subcategories varied from 1 to 1024, so the whole solution seemed to me quite impractical.

Fortunately, we could solve the customer’s requirement very easily using CloverDX. For example, there are (among others) two fields – category and subcategory – in your metadata coming into XLSWriter. Then, if you set File URL in the form of filename_#.xls, Data sheet set as $subcategory and Partition key as category, the writer will split records into files according to the categories and into datasheets according to the subcategories.

Finally, the customer came to a conclusion that one file with many records is better than dozens datasheets within dozens files with very few records.
