Sorting text is such a day to day activity that it always surprises me why Excel hasn’t provided a simple spreadsheet formula for doing it. Of course you can use the sorting menu command (menu > data > sort) but this requires manual steps (or VBA). Most of the times we get raw textual data from various sources and we need it to be sorted. While fooling with the COUNTIF() formula, I have realized a powerful yet little known feature that can be exploited to sort text using formulas.
We all know that countif() can be used to find the number of cells in a given range matching a criteria. But do you know that you can use COUNTIF() to find the number of cells in a range greater than or less than a particular value?
Well, that is the trick to sorting text. How?
For eg. assume range A1:A10 has c,b,d,f,h,j,e,a,i,g in them. When you write =countif(a1:a10,"<c") you will get 2 as the result.There are 2 cells with value less than “c”. In other words, the sort order of “c” in the given cells is 3 (since it has 2 cells less than “c”)
You can use this on your own list to fetch the alphabetical sort order of each text value like this:
Essentially the sort order formula looks like this: =countif(SORT RANGE, "<="&CURRENT CELL)
Once you have the sort order, arranging the cells in that order is a piece of cake. We just use VLOOKUP to do our job, like this: =VLOOKUP(1,SORT ORDER TABLE,2,FALSE). (PS: if you are worried about unique cells, which you should, then use this formula instead, =VLOOKUP(small(SORT ORDER COLUMN,1),SORT ORDER TABLE,2,FALSE)
What the heck is above formula doing? It is running a vlookup on the table containing original cells and their sort order to fetch the cell with sort order 1 (or the smallest sort order). Replace the 1 with 2 to get the next cell in the alphabetical order.
Download the workbook with alphabetical text sorting using formulas and see this in action.
Bonus tip: Instead of rewriting the vlookup formula with 2, 3, 4 as lookup value you can use excel's row() function to generate those running numbers for you. You just need to subtract correct value from the row().

I think the virtue of pie charts is precisely that they are difficult to decode. In many contexts, you have to release information but you don't want the relationship between values to jump at your reader. That's when pie charts are most useful.

Chandoo,
millions of ants cannot be mistaken.....There should be a reason why everybody continues using Pie charts, despite what gurus like you or Jon and others say.
one reason could be because we are just used to, so that's what we need to change, the "comfort zone"...
i absolutely agree, since I've been "converted", I just find out that bar charts are clearer, and nicer to the view...

Chandoo -
You ask "Can I use an alternative to pie chart?"
I answer in You Say “Pie”, I Say “Bar”.
This visualization was created because it was easy to print before computers. In this day and age, it should not exist.
I think the 100% Bar Chart is just as useless/unreadable as Pies - we should rename them something like Mama's Strudel Charts - how big a slice would you like, Dear?
My money's with Jon on this topic.
The primary function of any pie chart with more than 2 or 3 data points is to obfuscate. But maybe that is the main purpose, as @Jerome suggests...
@Jerome.. Good point. Also sometimes, there is just no relationship at all.
@Martin... Organized religion is finding it tough to get converts even after 2000+ years of struggle. Jon, Stephen, countless others (and me) are a small army, it would take atleast 5000 more years before pie charts vanish... patience and good to have you here 🙂
@Jon .. very well done sir, very well done.
good points every one...
I've got to throw my vote into Jon's camp (which is also Stephen Few's camp) -- bars just tend to work better. One observation about when we say "what people are used to." There are two distinct groups here (depending on the situation, a person can fall in either one): the person who *creates* the chart and the person who *consumes* the chart. Granted, the consumers are "used to" pie charts. But, it's not like a bar chart is something they would struggle to understand or that would require explanation (like sparklines and bullet graphs). Chart consumers are "used to" consuming whatever is put in front of them. Chart creators, on the other hand, may be "used to" creating pie charts, but that isn't an excuse for them to continue to do so -- many people are used to driving without a seatbelt, leaving lights on in their house needlessly, and forwarding not-all-that-funny anecdotes via email. That doesn't mean the practice shouldn't be discouraged!

Good article. Is it possible to do that with line charts?
Hi,
Is this available in excel 2013?
