Alright, first things first. Head over to your Glide app and look for that little "Settings" icon up in the top-right corner. Click on it. This will open up the app settings where you can tweak all sorts of stuff.

Next, in the settings menu, find the "Components" section. You’ll see a switch for the "File Picker" component. Go ahead and toggle that switch on. This will let users upload files to your app. Easy peasy.

Now, let’s add the file picker to your app. In the app builder, pick the screen where you want the file picker to show up. Click on the "+" button to add a new component and select "File Picker" from the list. Simple, right?

After you’ve added the file picker, you’ll need to configure it. Set the properties like what types of files you’ll accept (documents, images, etc.), and decide where in your Google Sheet the file URLs will be stored.

Make sure your app has the right permissions for file uploads. Go to the "Privacy" settings and check that the appropriate access level is selected. This way, users can actually use the file picker.

Time to test it out! Preview your app in the Glide editor and try uploading a document. Check to see if the uploaded file’s URL shows up in the specified column in your Google Sheet. Fingers crossed!

Once everything’s working smoothly, go ahead and publish your app. Share it with your users, and they’ll be able to upload documents using the file picker component. Voila!
