Add leading zero's

Anonymous — Sat, 16 Nov 2024 12:27:01 GMT

I have a text file containing a column "ID". Please see example below. The ID should be an integer with length 3. Now the problem is that some records have values which are two digits long. Is it possible to (in case the length is not three) add leading zero's, just to make it length(3)? I know this is possible with a custom java code (component), however I would like to fix this with a regular expression replace. Anyone some suggestions?
"ID","TITLE"
"123","Title 1"
"456","Title 2"
"78","Title 3"

Hi
If you want to have a value like "078", you have to change this column as String.

Thanks; forgot to mention, the column IS a string.

I use :
String.format("%3s", <your field> ).replaceAll(" ", "0")

String.format("%3s", <your field> ).replaceAll(" ", "0")

Thanks! Little improvement to your code:
String.format("%03d", Int.parseInt(row7.ID));
This will add "0"'s to your integer, with a maximum of 3 digits long.

Hi,

I also have the same doubt and try to get the desired output but get an error (Int cannot be resolved). So, I tried this:

String.format("%3d", Integer.parseInt(<your field>))

and it worked out successfully.
