Row height on list Sharepoint Online

Emil Rindell Try the solution given here using JSON formatting: Increase (not decrease) row height in a SharePoint list using JSON formatting 

OP in above thread applied this JSON column formatting to multiple lines of (plain) text column: 

{
  "$schema": "https://developer.microsoft.com/json-schemas/sp/v2/column-formatting.schema.json",
  "elmType": "div",
  "txtContent": "@currentField",
  "style": {
    "height": "auto"
  }
}

Note: Multiple lines of (rich) text columns does not support JSON formatting.
