Hi ! I would like to remove the "," at the very beginning of the concatenation.

I tried with the transformer "substringextractor" but I remove the "1" from my thousandth when there is no comma at the beginning.

I saw that there was a transformer "LastSectionOfStringRemover", maybe it exists for the beginning?

You can use a StringReplacer in the Replace Regular Expression Mode with the following text to replace:

^,

Alternatively, you can also use the AttributeTrimmer to remove a specific character from the left side and/or right side of a string.

Hi Chrisatsafe and Takashi!

Both solutions work, thank you !
