Sandbox solution deprecated already, you need either deploy SharePoint add-in part or SPFx solution.

  • Our organization is moving from SharePoint On Premises to SharePoint Online, so we want our visual web parts to be moved on SharePoint Online as it is. Please suggest a solution to add those web parts Nov 29, 2018 at 7:43
  • Not support anymore, have to re-write with either above two solutions.

Sandbox solution deprecated long back.

If you want to migrate in SharePoint Classic view - You have below option:

Content editor web part( where you can refer your files) SP hosted Apps. (SharePoint Hosted) Provider Hosted Apps( you need a server to host , for example - Azure) SharePoint Framework Apps( Client side Object Model)

If you are migrating in SharePoint Modern view - You have one option to deploy your code : SharePoint Framework Apps( Client side Object Model)

To deploy your app model you must have set you app catalog in your tenant.
