I sometimes use connectors and autoshapes in excel to make flowcharts for my projects. A little refined touch and you can have them looking nealy like the ones made in Visio. I say *nearly* because although everything moves, reshapes and resizes properly, the connectors still bend at 90 degrees unlike the ones in Visio which curve smoothly…..but nonetheless a small price to pay especially if you don’t have ready access to visio.
You can download a sample of Visio like flowchart in excel here.
I recommend that you also try Easy Flowchart, a free flowchart creating utility in Excel. I am sure you’ll like it !
