Hello,

I have a field in string, and in this field, i have different numbers (example : 0032345643).

I want to add "0" at the beginning when the number have only 9 characters, and add "00" at the beginning when the number have only 8 characters.

It's possible in dev tools ?  
have you an example of script for that ?

Thanks !

Hi @Fred59,

It is possible by transforming data with [scripted fields](https://www.elastic.co/guide/en/machine-learning/master/ml-configuring-transform.html):

Your script may look like

```
doc['your_field'].value.toString().length() == 9 ? "0"+doc['your_field'].value : "00"+doc['your_field'].value 

```

Regards, Dzmitry

Hello,

Possible to make this modification in dev tools for modifi the actual field et don't create a new field by scripted field ?

Because many visualisations use actually this field.
