Numbers
Add video and audio in Numbers for iCloud
You can add video and audio to a spreadsheet. When viewing your spreadsheet, you can click the play button on the video or audio objects to watch it or listen to it. You can also add video or audio descriptions that can be read by assistive technology (for example, VoiceOver).
Note: Video and audio files must be in a format that QuickTime supports on your Mac computer or Windows device. If you can’t add or play a video or audio file, on a Mac, try using iMovie, QuickTime Player, or Compressor to convert the file to a QuickTime file (with a .mov filename extension) for video, or an MPEG-4 file (with a .m4a filename extension) for audio. On a Windows device, try using QuickTime to convert the file to an MP4 or M4A file.
