Hi,
if I run check on this file

id,text
a,b
a,b,c

I have

mlr :  mlr: CSV header/data length mismatch 2 != 3 at filename input.csv row 3.

It would be great to have a structured output, to use it to run some automatic cleaning. Having something like

{
  "valid": "false",
  "errors": [
    {
      "row": 3,
      "message": "CSV header/data length mismatch 2 != 3 at filename input.csv row 3."
    },
    {
      "row": 9,
      "message": "....."
    }
  ]
}

I can run a loop to delete 3 and 9 rows.

And it would be great to have two parameters: one to have in ouput only the rows without errors, and one to have only those with errors.

Thank you
