The comma in format "#,###" make json object in trouble

[hyh888]

When I use  format "#,###" , it makes json object in trouble in browser. I think many users should have suffered for it.
Here is the code:
let gridColModel= [

{   "title": "production",
    "dataIndx": "actualProdTon",
    "width": "100",
    "dataType": "float",
    "format": "#,###"
}

];

For the template engine in my program regards "###" as comment symbol, so the js program was disabled partially.
Is there any other way to repalce format "#,###"?
