Hello @David74000,

Welcome to Plumsail Community!

Column formatting using the JSON object is supported in SharePoint 2019.

You need to download JSON schema for SharePoint 2019 following this link and upload it to SharePoint document library

Note that .json file extensions are not supported, thus you need to change the file extension to .js

And you can use this schema to change the create a link to open the file properties:

{
   "$schema": "{Link to the JSON schema}",
  "debugMode": true,
  "elmType": "div",
  "children": [
    {
      "elmType": "a",
      "txtContent": "Properties",
      "attributes": {
        "target": "_blank",
        "href": { "operator": "+", "operands": [ "/sites/{sitename/subsite}/_layouts/15/listform.aspx?PageType=6&ListId={ListID}&ID=", "[$ID]" ] }
      }
    }
  ]
}

Replace {Link to the JSON schema} with the complete URL to the JSON schema file,
{sitename/subsite} with the path to your site,
{ListID} with the library ID.
