Convert a xlsm to access

Hi All,

I've never used Access before so a complete noob.

I have an excel workbook with loads of VBA/macros within it. The workbook has approx. 10 sheets.
Currently we use the workbook via Teams so that multiple users can use it at the same time.
I want to make the workbook more stable due to the amount of usage it gets.
Do anyone know how I can take this workbook in its current state and transfer it over to Access.
The workbook took me approx 6 months to build so ideally would not like to start again on the Access platform.
Any help would be greatly appreciated.
