CSV mapper: introduce a computed mode allowing users to create their own computations for conditionnal mapping

[nino-filigran]

Use case

Users might have a variety of CSV. In order to know which entity is what in the csv we have introduced the conditionnal mapping. However to go one step further, we might have cases in which users would like to introduce some computations inside their csv in order to be able to verify some conditions. For instance, it could look something like

• If(contains(colA)= ".", "IPV4", "IPV6") and then use the result of this computation within a conditionnal mapping to be able to determine the type of entity.

This could serve not only within the conditional mapping, but also to build some custom columns.
