Important Microsoft no longer recommends creating and using Access web apps in SharePoint. As an alternative, consider using Microsoft PowerApps to build no-code business solutions for the web and mobile devices.
View and sort data online, using any device, in an Access web app—even if you don’t have Access. The fastest way to get started is to use a template.
Create an Access web app from a template
When you select a template, Access assembles an app that contains the tables you probably would have added yourself if you had started from scratch.
Note: To create an Access web app, you need Office 365 with SharePoint Online, on-premises SharePoint Server 2013, or SharePoint Server 2016 with Access Services and SQL Server 2012 (or higher).
Tip: If you need to close a database, select File > Close.
Open Access, and select a web app template. (Web app templates have a picture of a globe in the background.)
Tip: If you don’t see the template you want, under the Search for online templates box, select Databases. Then, to find database templates on Office.com, enter one or more keywords in the search box.
Enter a name for your new app.
From the list, select its location. (Or enter a SharePoint URL or an Office 365 URL.)
Then, select Create.
Create an Access web app from scratch
Creating an Access web app from scratch is very similar to creating one from templates. The biggest difference is that you create the tables in your web app.
Open Access, and select Custom web app.
Enter a name for your new web app, and select its location. Then, select Create.
Add structured or blank tables to the web app, or create tables from existing data sources. Search for a table template based on the type of information you want to track, create a table from the existing source data, or add a blank table to customize yourself.
