Preview / Evaluation in String Manipulation

Hello,

It would be great if we could have a Validation/Preview for String Manipulation. Similar to the DB Query reader. Tools like Tableau have this and its super helpful. Especially as you use things like IndexOf and have to calculate Substrings etc.

toInt(substr($$ROWID$$,
indexOf($$ROWID$$,“_”)+1
)
)+
($pageNumber$*60)-60

Thank you

I agree with you but not only that (I’m not using Tableau) - it will be very useful for almost all manipulation nodes, after applying changes, to see statistic: how many changes, how many rows are affected and so on (and that these statistics are accessible via node outputs?) …
