..."Organization":"Default Organization","Lifecycle Environment":"Library"...

n+1st time:
...\"Organization\":\"Default Organization\",\"Lifecycle Environment\":\"Library\"...

2. Monitor -> Report Templates -> generate Host Statuses

4. Download the file
5. Click Download and download the file again

Quotation marks escaped
