Yes, you can certainly import your MS Access data into Airtable!
On your Airtable home page, select “Add a Base”, then “Import Data”, and then you will see the option to import from Microsoft Access. You can upload your data as a CSV file, or you can paste your table data directly into the dialog box.
If you have multiple tables that you would like to import, you can import them into separate tables in your base. Note that any existing relationships between your tables will need to be recreated using linked record fields.
Please note that there is currently a 5MB limit on CSV uploads.
