Num Sum: Throwaway Web Spreadsheets

Category: Showcase

Num Sum is a new ajaxian web spreadsheet in the “Ajax Office” vein, brought to us by TrimPath.

You can simply create spreadsheets on the fly and name them if you want to keep and share for awhile, or just have one use and move on.

Since this is the participation web 2.0:

Or, you could just use Excel and share that? ;)

hmmm, on this one i am going to say ajax is not the correct implementation. compare numsum to even the free spreadsheets (gnumeric, openoffice calc) and you will find hundreds of missing features. so i must ask who is this tool really for and what is the point, or are we just demonstrating a clickable grid in dhtml with simple numerical functions? also javascript is not a strong numerical language, its just not the right tool for the job.

so while i think numsum is cool, it is also useless.

I’m thinking a better implementation would be an Excel web based file viewer, where a user could have some web space and easily upload and share Excel files via web based view. That would by pass the obvious editing problem associated with an AJX implementation of a full edit environment

I agree that it’s not the most useful webapp, but it would have some potential applications as part of a larger webapp – at least I know I could make use of it.

Hi, I’m the guy who wrote it, originally, to see how far browser/dhtml/ajax technologies could be pushed circa 2005. I agree that Num Sum is missing tons of features compared to Excel. But, I also say that Excel overshoots many of its customers, in Innovators Solution terms.

Also, I remember that early webmail services like HotMail really lagged against the hundreds of features of desktop apps like CC/Mail and Outlook. And today, many of us prefer webmail.

Folks are already using Num Sum not for fancy financial modeling, but for simple budgeting, estimating, scheduling, projections and to make simple databases.

steve – nice work by the way, in terms of a demo. but once again, even lacking features, i would say the lack of strong numerical precision and functionality in javascript is the biggest issue. this even dogged java for years.

Clean, fast and simple spreadsheet.

With openoffice / excel / CSV export this could be quite a nice little app.

Nice work

Interesting and something I could find really useful. The problem is to avoid putting too much functionality on the client. I would like to to give the user a familiar spreadsheet interface with some basic functions and keep the calculation engine on the server. This is a challenge to do in Excel unless you are using the latest versions and want to use .Net, which none of clients are doing. Perhaps I have a specific need in mind and this might be the solution – I will be trying this out.
