Pentaho Kettle conversion from String to Integer/Number error
Solution 1
I have solved it. The idea is similar to what @nsousa suggested, but I didn't use the Trim option because I tried it and it didn't work on my case.
What I did is specify that if the value is a single space, it is set to null. In the Fields tab of the Text File Input, set the Null if column to space .
Solution 2
That value looks like an empty space. Set the Format of the Integer field to # and set trim to both.

I am new to Pentaho Kettle and I am trying to build a simple data transformation (filter, data conversion, etc). But I keep getting errors when reading my CSV data file (whether using CSV File Input or Text File Input).
The error is:
... couldn't convert String to number : non-numeric character found at position 1 for value [ ]
What does this mean exactly and how do I handle it?
Thank you in advance
