Ah, you thought I will let you go to the next decade without a “year in review” post? No so fast my friend, not so fast.
[This post is a bit long by our standards, but full of gooey excel goodness. So get a cup of coffee or choco and get going]
January 2009
The year 2009 has been pivotal in PHD’s life. It all started with a friendly email from Microsoft on Jan 1st telling me that PHD become an MVP. I felt wonderful knowing that. Even though the award meant little in terms of benefits, it is a great tribute to our little community and the passion we share here.
Later in the first week we wrote a post on how to make combination charts in excel. The discussion on combo charts continued throughout the year, so much that when I posted a holiday greeting card at the end of the year, Santhosh, one of our regulars said that they card looked like a combo chart.
Most importantly we have crossed the milestone of 2000 RSS subscribers in the Jan 2009. To celebrate that I posted one hundred excel tips. That was fun (plus Jo hated me for sitting in front of computer that long).
February
February is fun. I started off the month with an excel twitter client. Which became a wild hit on internet (ok, not so wild, but few of the other blogs in excel community did mention it. Also, JP, the rockstar VBA blogger at codeforoutlookandexcel made an add-in out of it)
Later in the month I got too excited to discover that you can use excel data filters to make a dynamic chart. By far the cheapest and easiest way to make a dynamic chart. We continued the discussion on dynamic charts for the rest of the year and posted several ways to make them.
March
I celebrated the one year anniversary of “conditional formatting rockstar” post by writing 5 more posts on excel conditional formatting. The series started with conditional formatting basics and went on to talk about how you can solve 4 most common problems using excel CF.
We also started writing about excel array formulas and continued that discussion off and on. Array formulas area fun and easy to write (once you have the basics right).
April
This has been a dull month what with my transfer from India to Sweden and sudden lack of internet connectivity. Despite all that we wrapped our first visualization contest on budget vs actual charts and posted some really excellent charting alternatives to the familiar problem.
PHD is also featured on Lifehacker for the Excel Formulas Errors – How to handle them? post.
May
We have proposed “Tweetboards” as an alternative to traditional dashboards and generated good bit of discussion in May. Later several readers emailed me their tweetboard implementations. Slowly tweetboards are spreading in the wild 😉
We also rounded up all the Excel 2007 Productivity Tips.
June
I have stared the Project Management using Excel series in this month with Project Management Gantt Charts. The 6+1 posts soon became legendary and helped me launch the project management templates. In total these posts had more than 200 comments, 150k page views in a short time.
June also was the best month PHD’s history as the blog got featured again on Lifehacker and Delicious home pages for the Excel Mouse Tricks post. Later that month we have rounded up all the techniques you can use to convert excel files to pdfs.
July
We focused on charting more and had the 14 skills you must have for making better charts. I have also written about the all too familiar sumif with multiple criteria problem and some formula solutions for it.
Later that month my post on Using Excel Goal Seek and Finding how much you need for retirement got mentioned in Lifehacker and fetched me a ton of new visitors.
August
Thanks to Aaron, who guest posted about excel waterfall charts in August. In august, I have turned my attention towards the pivot tables and wrote Excel Pivot Tables Tutorial. I have been playing with pivots off and on for a while and this post was my first serious attempt to explore the features. Later I wrote more about them and I am planning to explore pivot tables further in 2010.
In august, we have also crossed the 5000 RSS subscriber mark and celebrated it with a huge contest. Later that month I have wrapped up all the contest entries in the Excel Formulas – 29 tips post.
September
I have started the month with a discussion on Pareto Charts and how to make them in excel. Later that month I wrote about Excel Data Tables features. Both of these posts attracted a lot of discussion and helped me learn valuable new tricks in excel.
Later that month, on September 24th, I became a dad. My life has been the most wonderful and beautiful ever since.
October
In October we wrapped up the project management series with a Project Status Dashboards using Excel. Later that month I have launched the project management templates for excel product. I met several new customers and started to believe that I can make a living out of this blog.
November
In November, we started our most ambitious visualization challenge ever with the Zoho Sales Data Visualization challenge. We now have more than 30 excellent entries and I am waiting for Jan4th when we announce the voting for winner.
Also I have posted about the sumproduct formula and reviewed excel 2010.
December
We started the month with a discussion on using drawing shapes along with charts to make better dashboards. Later in the month I have written about making a quick thermo-meter chart and posted alternatives to compare targets using charts.
Finally I have released the free 2010 calendar excel for you to download and print copies.
To wrap up,
I liked this year thoroughly. Personally it has been nothing short of an exciting ride. We became parents, Jo got promoted, we purchased small piece of land (where we are going to build our dream house) and things couldn’t be better.
Blogwise, the year is equally exciting. I am extremely thankful to all of you for being there for me and encouraging me to learn and share. I met several new people thru this medium and made new friends.
I hope the year had been a memorable experience for you as well.
I sincerely wish you a prosperous new year 2010. Thank you.
PS: Those of you who visited the site yesterday must have seen the nagging “Database error”. I am sorry, but there was a problem when I moved the blog to a different server and the DB went down for almost 24 hours. Now it is up and running smoothly. Let me know if you see something funny.

Why not let the TIME function take care of the math:
=TIME(LEFT(TEXT(A1,"000000"),2),MID(TEXT(A1,"000000"),3,2),RIGHT(TEXT(A1,"000000"),2))
I was going to point out the same thing, except to note that useing the time function and doing the divide method are not interchangeable.
I have spent hours investigating a spreadsheet working with a couple of years worth of hourly data, and found that the reason things weren't working is because the rounding on the divide method is only close to the correct time values. In order to have it work for comparisons, (like sub-totaling by time value, or pivoting) you MUST use the TIME function.
Great use of the TEXT function, Hui. I will be using this concept for sure.
Why not just.
=TEXT(A1,"00\:00\:00")*1

Elegant!
Hi Elias,
I tried to use your formula. But, it doesn't seem to work for me. I am getting an error message "The formula you typed contains an error". It seems I have the problem in using \: in the format. How can I overcome this?
Thanks
Manick, it isn't the /: that causes the problem. If you copy/paste it, you're getting “'s instead of the actual quotation marks that Excel uses. Change the quotation marks by deleting from the pasted formula and retype them.
Hi Manick...
use this alternate formula :
=1*TEXT(A1,"00"":""00"":""00")
note twice double quote each side of :
@Manick,
Did you copy the formula and pasted in Excel or did you typed? Also, do you use , or ; as separator of arguments?
Regards
@Elias: I had no problem using your formula, in fact, I have used your method to convert a number such as 20120419 to an Excel date using =TEXT(A1,"0000\/00\/00")*1. Thanks for posting.
@Joe: For date convertion you can use this as well.
=TEXT(A1,"00-00-00")*1
Regards
Sweet! It appears this also works with =TEXT(A1,"0-00-00")*1. I come from the old days when you counted every byte. I also like to try an make formulas as small as possible for the fun of it 🙂
Elias's suggestion is the simplest, but here is yet another way with TIME and MOD functions...
=TIME(MOD(A2/10000,100),MOD(A2/100,100),MOD(A2,100))
Since the seconds appear to always be 0, why not simply the input to minutes and above and save yourself the trouble of typing those zeroes...
0 => 0:00
1 => 1:00
10 => 10:00
100 => 1:00:00
etc.
Then just use this formula...
=TEXT(A1,"0\:00\:")*1
@ Rick, the numbers to convert are no typed, they are imported. Then your formula will return the wrong result.
Regards.
Hmm! My formula lost some backslash-zero combinations (two of them to be exact). The formula was supposed to be this...
=TEXT(A1,"0\:00\:\zero\zero")*1
where the words "zero" should actually be the number 0. Another way to write the formula is this...
=TEXT(A1,"0\:00\:""00""")*1
Hi Master,
While writing the formulae you have considered only upto "seconds factor" . I think you should take the centi-seconds factor also to achieve best results. Please look into it and rectify the problem...?
For Example.
In horse racing timings are noted in minute, seconds and centi-seconds, like if a horse finished in 70 seconds over a scurry of 1200 metres, is noted as 1.10 min. Nowadays it is noted in centi-seconds everywhere, like 70.00 if you want to convert it to centi seconds (should multiply by 100) = 7000 centi seconds. If you put this figure into your formula as a general number (7000) it will return as 1:10:00. As per your formula, it should be taken as 1 hour 10 seconds 0 minutes. However for a racing enthusiast like me it can be taken as 1 minute 10 seconds also.
Just look what happens if we race goers use this figure as 7000 centi seconds in your formulae, it will correctly show as 1 minute 10 seconds(?) Suppose a horse finishing over a 1200m in 70.60 seconds or in racing terms written as 1.10.60 mins, where 1 minute 10 seconds, & 60 centi-seconds can be counted as 7060, if you put this figure in the formula it will return as 1 minute 11 seconds, that is correct.
My point is if you can incorporate Centi Seconds in the formulae, it would be of great help to us also.
Thanks and regards.

Awesome techniques !
I tried with 235960 just to see if it will fail but this is great.
Although a little longer, this too work:
=CHOOSE(LEN(A2);A2/(24*3600);A2/(24*3600);LEFT(A2;1)/(24*60) + RIGHT(A2;2)/(24*3600);LEFT(A2;2)/(24*60) + RIGHT(A2;2)/(24*3600);LEFT(A2;1)/24 + MID(A2;2;2)/(24*60) + RIGHT(A2;2)/(24*3600);LEFT(A2;2)/24 + MID(A2;3;2)/(24*60) + RIGHT(A2;2)/(24*3600))
Converting uneven Text Strings to Time I have imported some data that comes in as a number that I need to convert to h:mm.
Just come across this while googling
find interesting challenge and come up with this
=TEXT(TEXT(SUBSTITUTE(A1,RIGHT(A1,1),""),"000000"),"00\:00\:00")
I need to convert a string of numbers representing average minutes, to reflect correct time values. For example, the numbers below currently represent 5.79 minutes, 15.82 minutes, etc.
I need to convert these values to their correct corresponding value within time parameters. So 5.79 would be something close to 5 minutes and 45 seconds.
5.79
15.82
3.92
12.40
6.70
3.62
I know there has to be a way to compute this in Excel, it can do anything, I believe!
Thank you for any and all assistance~
@Renee... You can use a formula like this. Assuming A1 has the minutes.seconds,
=INT(A1) + MOD(A1, 1)*0.6
If you want to see it in 5 minutes 45 seconds format, use
=INT(A1) & " mins " & ROUND(MOD(A1, 1)*0.6,2) & " secs"
