XLS

This filter allows you to extract all the rows from a Excel file.
Based on the qax-os/excelize library.

Parameter	Type	Default	Description
target	STRING	“main”	the field of the Message that should be used for the filter (it could be the `main` or and extra field)
filename	STRING	empty	the filename of the XLS file to parse (supports Golang templates)

... | xls(target="{{ .extra_field }}") | ...

The filename field override the target. They are mutually exclusive, so you can specify only one of them.

The filter produces one Message for each row of the XLS file.
