Is it possible, update multiple spreadsheets at one time?

[Butcher1]

I'm a layman when it comes to macros and not sure what is and isn't possible.

The (hypothetical) situation is I host a spreadsheet on my website. Users are able to acess this spreadsheet, put their own data into it and save it to my website. Lets say I have 100 customers and I decide to update the spreadsheet with a new feature. Is it possible to update my customer's spreadsheets all at once, or would I have to access each individual's spreadsheet to make the change?

[vba_php]

can you post the site's url? a screenshot of what is going on?

how can you do this?

you said it's a hypothetical. are you not currently doing this?

[Butcher1]

are you not currently doing this?

No I am not doing this currently. I am hoping it is possible though.

[vba_php]

No I am not doing this currently. I am hoping it is possible though.

what exactly will you be doing? that is not clear at all. just saying ""keep a spreadsheet on a website"" says nothing.

- embedded?
- linked to something else?
- attached as a file with an extension?

etc, etc....

I host a spreadsheet on a website. You pay a monthly subscription fee to use it and save it as vba_php's_personal_copy (restricted to being saved only to my website cloud space). You enter your data and have a sheet that will display your data in an easy to view format. I have 100 other people who also subscribe to my spreadsheet and are putting their own data into their personal copy of the spreadsheet. Eventually I decide to update my master copy of the spreadsheet. To update every customer's spreadsheet with new formulas, would I have to access each spreadsheet individually, or could I just update the master spreadsheet and run a macro to update all customer's spreadsheets at one time?

This video seems to suggest it is possible, but I don't know enough to understand enough to know if the method in the video would work in my situation.

look at this point in the video:

he's talking about looping locally. doing it in the cloud is completely different. VBA is not a cloud language. thus, I seriously doubt it would work. but I could be wrong. if you have an FTP like filezilla, you can test it on your own anyway. why not do that?
