Hi @Jan_Svajcik,

Using `JSON Input` it would be something like this:

`{ "script" : "doc['filesize'].value / 1000 / 1000 / 1000" }`

But I think you should better instead configure this `filesize` field to use `bytes` formatter. Then this field will be nicely displayed everywhere in Kibana's UI.

To do this:

Management -\> Kibana -\> Index Patter -\> Pick you index pattern -\> find `filesize` field and click edit -\> in `Format` select `Bytes` and then `Save`.

Then in your vis it should be nicely formatter as "392Gb" without a need for `JSON input`

More info about field formatters: [https://www.elastic.co/guide/en/kibana/current/field-formatters-numeric.html](https://www.elastic.co/guide/en/kibana/current/field-formatters-numeric.html)

Hope this is helpful.
