Logstash doesn't have any datatypes that serialize to `14,960,923,573 long`. What format is this coming in as? Is it a string of characters (`1` `4` `,` `9` `6` `0` `,` `9` `2` `3` `,` `5` `7` `3` SPACE `l` `o` `n` `g`)?

If so, the following should work by replacing any comma surrounded by digits, or any trailing `<SPACE> long`, with an empty string:

```auto
filter { mutate { gsub => ["user_id_s", "(?:(?<=[0-9]),(?=[0-9]))|(?: long$)", ""] } }

```

NO. Its a long value coming as follows in discover of kibana

```auto
14,960,923,573 

```

I just want a long value or string value as

14960923573

Can you check kibana index options, there might you able to remove those extra commas

Stack Management -\> Kibana Index Patterns -\> Your index -\> Your field "Set Format" = "0"

this will remove commas, but keep that in mind, this is only for kibana
