It seems that they are related to ANSI Colors in standard Windows shell...

Using python, json.load() or json.loads() should unescape the data.

Hi David, I've written here after getting exceptions from json.loads()

At the end I've found that it may be solved just adding --response-format-json (short : --rfj) option to command.

So my full command becomes

zowe zmf get component -c "PYTCC001" -t "COB" -p "BKA 000435" --rfj --zmf-profile "zmfx" > K:/projectsout/mainframe/cmnrestsample/testhttprfj.json

In this way I get a clean json because the "windows console colours escaped content" is assigned to property "stdout" and the json received has a specific "data" property that is a "clean" object

{
  "success": true,
  "exitCode": 0,
  "message": "",
  "stdout": "\u001b[35m{
  ....
  ....
  "stderr": "",
  "data": {
    "message": "CMN8700I - LIST service completed",
    "reasonCode": "8700",
    "returnCode": "00",
    "result": [
      {
        "applName": "BKA",
        "baseDateLastModified": "20230919",
        ...
             }
    ]
  }
}
  

And also using json.loads() now it's ok without exceptions.

json.load() takes in an input file whilst json.loads() takes in a string.

Yes, of course.

I've tried both.

The sample in this post (as the original sample) uses a file and so a json.load().

But usually I run with

and I may use json.loads() ....
