Checkbox Help

In Excel, if you want a checkbox to automatically appear in a new row when data is added, you might need to use a combination of table formatting and VBA (Visual Basic for Applications) scripting. Excel doesn't provide a feature to automatically insert form controls like checkboxes based on cell data changes by default.

Here's how you can do it in general:

Convert your data range into a Table:

This can help in maintaining the structure of your data and can facilitate the addition of new entries.
To do this, select your range and then go to the 'Insert' tab and click on 'Table'. Make sure the "My table has headers" option is checked.
Use VBA to add checkboxes:

You would need to write a VBA macro that triggers whenever a new row is added to your table. This macro would insert a checkbox in the specified column of the new row.
To access the VBA editor, press ALT + F11. Then, you can insert a new module and write your macro there.
The macro would need to be associated with the worksheet's Change event or, more specifically, the Worksheet_Change or Worksheet_TableUpdate event.
