ag-grid (React) having custom column for exports

Question

Say I have the following data:

[
  { name: 'Cesar', date: '2023-10-10 05:10AM' },
  { name: 'James', date: '2023-10-11 10:10AM' }
]

and I have the following columnDefs for ag-grid:

[
  { headerName: 'Name', field: 'name' },
  { headerName: 'Date', field: 'date' }
]

If I export it (CSV or Excel) I get the same exact 2 columns, which is the default behavior.

But, how can I have the export functionality (CSV and Excel) to split the date column into two columns? This is the data structure we expect to see in the exported files.

| Name  | Date       | Time    |
| ----- | ---------- | ------- |
| Cesar | 2023-10-10 | 05:10AM |
| James | 2023-10-11 | 10:10AM |

Things I've tried

1. processCellCallback and processHeaderCallback to split the date column into 2 columns; but the "2 columns" are rendered in the same column 👎

two columns in one

2. I tried adding a third column to my columnDefs which is hide: true and lockVisible: true:

[
  { headerName: 'Name', field: 'name' },
  { headerName: 'Date', field: 'date' }, 
  { headerName: 'Time', field: 'date', hide: true, lockVisible: true } // with the right getter
]

This works partially because the column shows up in the Column Menu columnsMenuTab column showing in the menu

The checkbox is disabled, so the column cannot be shown ever; but we need the "time" column to be only available on the exported files, not in the UI

Congrats! You're very close to solve this puzzle.

suppressColumnsToolPanel

Set to true if you do not want this column or group to appear in the Columns Tool Panel.

{ 
  headerName: "Time", 
  field: 'date', 
  hide: true, 
  suppressColumnsToolPanel: true // this one
}

Here's an example
