Hello All,

i have a requirement where i need to allow external users to upload documents along with some meta data values to the library. i know its achievable by power apps but right now we don't have license for external user to access the power apps. we may need to create some kind of page to allow them upload and enter meta-values into library. what are the options available to develop such kind of solution for external users in SharePoint online? it would be greatly appreciated if you can provide any documentation or steps. Below is the UI that i am looking for.

Thanks in advance

    Hi @Raki ,

    Why don't you let the external users go to the library and upload documents there directly? This is much easier.

    To develop such app with the UI in modern page, you may need to use SharePoint Framework to build your own web part.

    In spfx, you can use PnP/PnPjs to upload files to library: https://pnp.github.io/pnpjs/sp/files/#adding-files

    Hi @Raki ,

    I would recommend that you'd better ask the developers in your company to develop the spfx web part. If you do not have developers, Spfx is not recommended.

    Here is another easy workaround for you:

    You could create another library(library 2) for exteranl users to upload files. Once there is file uploaded to the library2, use flow to move the file to library1. And the external users won't see the library 1 and folders. They just see an empty library 2.
