Solution 1Recommended

Duplicate and Modify an Existing Timeline Style

The most effective way to unlock custom style settings on Mac is to duplicate an existing Timeline style and adjust its properties.

In Excel for Mac, the 'Custom' style category remains hidden until you manually create a duplicate of one of the default styles provided by the application.

1
Select the Timeline

Click anywhere on the inserted PivotChart Timeline to reveal and activate the Timeline tab on the Excel ribbon.

2
Duplicate a Preset Style

Navigate to the Timeline Styles gallery on the ribbon. Right-click on any existing style option that closely matches your desired look, and select 'Duplicate' from the context menu.

3
Locate the New Custom Category

Excel will automatically create a copy of the style and generate a new 'Custom' category within the Timeline Styles menu.

4
Modify the Style

Right-click the newly duplicated style under the Custom category and select 'Modify'. You can now adjust fonts, borders, and fill colors to perfectly suit your needs.

Duplicate and Modify an Existing Timeline Style
Automatic Application: Any formatting changes you save to this newly modified custom style will be automatically applied if the Timeline is currently using it.

Frequently Asked Questions

Why isn't the custom Timeline style option visible by default on Mac?

In Excel for Mac, the 'Custom' category within the Timeline Styles gallery is only generated after you duplicate an existing preset style. Once triggered, the custom category remains visible for that workbook.

Can I use my custom Timeline style in other Excel workbooks?

Custom Timeline styles are saved locally within the specific workbook where they are created. To use them in a new file, you need to save the current workbook as a template or copy the customized Timeline into the new workbook.

How do I delete a custom Timeline style if I no longer need it?

Open the Timeline Styles gallery from the ribbon, right-click the specific style located under the 'Custom' category, and select 'Delete' from the drop-down menu.

Does modifying a custom style affect other Timelines in the workbook?

Yes, if you have multiple Timelines in your workbook that use the exact same custom style, modifying that style will instantly update the appearance of all connected Timelines.
