Google-sheets – Populate a Google slide automatically via Google spreadsheet

This is currently not a Google Docs feature (and not possible) based on online documentation and no better answer. Apparently, this worked at one point in Google Docs, but it required viewers to use Google Talk (and this combination was buggy at the time).

An alternative I went with is PowerPoint 2010, which comes with a feature to broadcast slideshows to users over the Internet.

You can't "push" a value (say from master spreadsheet to another) but you can "pull". So if A1 in Sheet1 is say 333 you can call that up in another sheet with =Sheet1!A1, or if say 01/01/1900 in Sheet1 you might give that a name, say bDay and use =bDay in another sheet to call up 01/01/1900.

Unfortunately I am not aware of a 'Group' facility for New Google Sheets (such as Excel has) and whatever you do seems will be required for each individual spreadsheet separately.
