Sumter is a bookmarklet that sums up all the numbers in your text selection. It can also be embedded into pages. Try the demo!
I often find myself wishing I could quickly add up some numbers on a Web page without transferring them to a spreadsheet. The most common example is when I'm reading a credit card statement online:
|03/01/2013||B&H DAIRY LUNCH||$12.49|
|02/26/2013||AMAZON WEB SERVICES||$0.25|
|02/26/2013||ABC BEER CO||$18.17|
|02/18/2013||PRET A MANGER||$6.93|
|01/30/2013||UTRECHT ART SUPPLIES||$19.40|
I'd really like to know how much I spent in February. Sumter lets me highlight the numbers I'm interested in and a total is displayed in the upper right-hand corner of the page.
Sumter can also handle select other currencies (detection is improving) and raw numbers. It will keep the totals separate.
|Dollar $||Pound £||Euro €||Yen ¥||Raw|
It adds each total together for a grand total but doesn't convert currencies.
Sumter is new. Let me know how it can be improved by opening an issue.
