There is a new topic by Schneider315 available at the DataCleaner forum: Simple 
"Is a column a valid integer?"

-------------------

I might be missing a trick, jsut started using this looking for one of the most 
simple validations is a column within a CSV file an integer. 

All are defined as string I changed one row to contain an a but cannot get teh 
DataCleaner to identify this.

Convert to number, shows up nothing instead it chops it at the 'a'
You can only do a number range conversion afterwards which is no use.

Ideally I'm looking for a VALID / INVALID filter on strings if they match an 
integer (Similar to is_number() in SQL)
