Hi,
I'm not sure how the table should be transformed.
Do you need to add the area name to the "Area" column like this?
Takashi
You can achieve this by reading the column "Area n." into a variable for each occasion the value is not a number.
You parralely (..is that a good word??) read the variable (using a VariableFetcher) into Area attribute.
Or you can simply use a conditional attribute creator with adjacent feature reading. (though with big data this will use more memory,( i have scripts that crash on memoryusage when using adjacent featuresettings)
Takashi,
Yes, It should looks like on your picture...
This is a solution example based on Gio's suggestion - VariableSetter/VariableRetriever.
