           {
            "ID": "85018",
            "FileLeafRef": "read only"
           },
           {
           "ID": "85091",
           "FileLeafRef": "completed"
           }

You can try JSON.parse

 const data = `<html> <body> <script type="text/javascript"> var g\_deferData= "testdata"; var g_listData = {"wpq":"","Templates":{},"ListData":{ "Row": [ { "ID": "85018", "FileLeafRef": "read only" }, { "ID": "85091", "FileLeafRef": "completed" } ]} } <\/script> </body> </html>` const div = document.createElement("div") div.innerHTML=data; let g_listData = div.querySelector("script").textContent.split("g_listData =")[1] console.log(JSON.parse(g_listData))
