General method: use a third-party class library (POI or HSSFWorkbook, etc.) to read the sheet and cell information of the excel file, traverse cells to read desired data according to the rules, and structure the table data. However, due to the lack of rich function class library of the program language, hard coding is still needed, and the workload will be relatively large.

It would have been much simpler to deal with such problems if you had used esProc SPL. It can easily read Excel files and structure the table data. For example, the content of the file item.xlsx is as follows:


The structured effect is shown as follows:


To deal with the above problem, esProc SPL only needs 2 lines, and the code is as follows:






In fact, there are many similar structured problems, and it will be very simple to use esProc SPL. Please refer to Parsing and Exporting Excel Data in SPL.
