How to convert ms-access

I wrote a ms-access application, named boeket.accdb ,
How do I convert it?

Hello,

You can create a connection to you Access file from Base, However this will only get you a connection to the table data. All the remaining information must be done anew in Base - Forms, Queries, Reports.

You can also transfer data to a database attached to Base via Calc. LibreOffice documentation here → LibreOffice Base Guide

In the mean time, I asked another person for this, and suggested him to use libre-office,
thanks for your reaction
