According to my tests, try with the single quotes:
```auto
mutate {
rename => { '[test][rex-platform"\\"]' => "[test][rex-platform]" }
}
```

```auto
rename => { '[test][rex-platform"\]' => '[test][rex-platform]' }
```
Still , if issue persists please share the debug screens as requested by Rio.

Thank you so much, fix the rename field. How about in the value field? It’s still `Windows““,`

Hello,
For value you can try to use gsub
```auto
rename => { '[test][rex-platform"\]' => '[test][rex-platform]' }
gsub => [
'[test][rex-platform]', '"', '',
'[test][rex-platform]', ',', ''
]
```
Thanks!!
