Hi @Keith Sublett ,
Good days. Welcome to Q&A forum!
In SharePoint’s modern list view, Yes/No columns are treated as booleans (true/false), so you can test for true.
Please follow these steps:
- Open your list.
- Click the column header (e.g., Title) and choose Column settings > Format this column.
- Select Advanced mode.
- Paste the following JSON:
{
"$schema": "https://developer.microsoft.com/json-schemas/sp/v2/column-formatting.schema.json",
"elmType": "div",
"style": {
"text-decoration": "=if([$Completed] == true, 'line-through', 'none')",
"padding":"0 45px",
"font-size":"20px"
},
"txtContent": "@currentField"
}
And the result:
Hope this information helps.
