What does it mean if regex did not successfully parse records but there is no error?

[Rajko]

I have a complex regex and get the following message... what it does it mean that 525 were not parsed? How do I find out which 525?

Thank you!

@Rajko,

Could you check the column generated by the REGEX if there is a NULL values.

Hope this helps!

As @messi007  suggested, insert a browse tool after you RegEx tool, the output columns with Null are the ones note being parsed.

Or to use a filter.

Got it, so it just means the regex didn't match any groups? Makes sense... thank you!!
