HI All

Currently after input i get data in this format

```
{
"csvdata" : "col1","col2","col3"
}
{
"csvdata" : "col1row1","col2row1","col3row1"
}
{
"csvdata" : "col1row2","col2row2","col3row2"
}

```

How should i club this mutiline event to a single line at filter level?  
What filter i use it to make it work?  
My expected output is

> {  
> " **csvdata**": "col1","col2","col3"  
> "col1row1","col2row1","col3row1"  
> "col1row2","col2row2","col3row2"  
> }

Thanks

That is not valid JSON.

Hi @Badger

I mean to say this way, my expectation is this format of json, please consider this

> {  
> " csvdata ": "col1,col2,col3\n  
> col1row1,col2row1,col3row1\n  
> col1row2,col2row2,col3row2"  
> }
