_Threaded Comments_
Introduced in Excel 365, threaded comments are plain text comment snippets with
author metadata and parent references. They are supported in XLSX and XLSB.
To mark a comment as threaded, each comment part must have a true `T` property:
```js
if(!ws.A1.c) ws.A1.c = [];
ws.A1.c.push({a:"SheetJS", t:"This is not threaded"});
if(!ws.A2.c) ws.A2.c = [];
ws.A2.c.hidden = true;
ws.A2.c.push({a:"SheetJS", t:"This is threaded", T: true});
ws.A2.c.push({a:"JSSheet", t:"This is also threaded", T: true});
```
There is no Active Directory or Office 365 metadata associated with authors in a thread.
#### Sheet Visibility
Excel enables hiding sheets in the lower tab bar. The sheet data is stored in

_Threaded Comments_
Introduced in Excel 365, threaded comments are plain text comment snippets with
author metadata and parent references. They are supported in XLSX and XLSB.
To mark a comment as threaded, each comment part must have a true `T` property:
