The other day I had to make an excel sheet for tracking all errors across one of the applications we are doing for our customer. The format was something like this,
We wanted to use a consistent message id format [4 digits: 0001, 0002, … , 1000 etc.]. Now I do not want to type “0001” in excel, instead I wanted to type 1 and I want excel to convert that to 0001 for me. So I started looking for a custom cell format and dug a little deeper to understand those. I thought it would be nice to share them to you all.
First take a look at how the cell formatting dialog box – number tab looks like:
Now apart from the built in types General (leave excel to guess the data format), number, currency, accounting (uses the separators, () notation etc.), date, time, percentage, fraction, scientific, text there are 2 interesting types of formating.
Special: Used for phone number, zipcode, social security number formats depending on the locale you select. For eg. for US they would be phone number [xxx-xxx-xxxx], ssn [xxx-xx-xxxx], zipcode[xxxxx, xxxxx-xxxx].
Custom: Used for creating your own cell formatting structure. This is a bit like regular expressions but in entire microsoftish way. Any cell custom format code will be divided in to 4 parts : positive numbers ; negative numbers ; zeros ; text. If your formatting codes have less number of parts (say 1 or 2 or 3) excel will use some common sense to find out which ones are for what.
Ok, without further confusion, this is probably how you can use the custom cell formatting feature in Microsoft excel.
Some explanation that you can skip if you already get it
- For formatting a number [eg. 1] to fixed number of digits [eg. 0001] you have to use 0000 as the custom formatting code
- For formatting a phone number [eg. 18003333333] to a standard phone number format [eg. 1 800-333-3333] you have to use 0 000-000-0000 as the custom formatting code
- To fill rest of the cell with a character of your choice [eg. *] you have to use @**(this applies for text inputs)

Hi Purna..
Again a great tip.. Its a great way to convert Fractional Time..
By the way.. Excel has two great and rarely used formula..
=DOLLARFR(7.8,60) and =DOLLARDE(7.48,60)
basically US Account person uses those to convert some currency denomination.. and we can use it to convert Year(i.e 3.11 Year = 3 year 11 month) and Week(6.5 week = 6 week 5 days), in the same manner...
This doesn't work for me. When applying the custom format of [h]:mm to 7.8 I get 187:12
Any ideas why?
@Jason
7.8 in Excel talk means 7.8 days
=7.8*24
=187.2 Hrs
=187 Hrs 12 Mins
If you follow Chandoo's instructions you will see that he divides the 7.8 by 24 to get it to a fraction of a day
Simple, assuming the fractional time is in cell A1,
Use below steps to convert it to hours & minutes:
1. In the target cell, write =A1/24
2. Select the target cell and press CTRL+1 to format it (you can also right click and select format cells)
3. Select Custom from “Number” tab and enter the code [h]:mm
4. Done!
Hi, sorry to point this out but Column C Header is misspelt 'Hours Palyed'
good one
So how do I go the other way and get hours and minutes to fractional time?
If you have 7.5 in cell A1,
- Use int(A1) to get the hours.
- Use mod(A1,1)*60 to get minutes.
If you have 7:30 (formatted as time) in A1
- Use hours(a1) to get hours
- Use minutes(a1) to get minutes.
I had the same issue. You can solve it by changing the format as described above:
Right click cell > Format Cells > (In Number tab) > Custom > Then enter the code [h]:mm
([hh]:mm and [hhh]:mm are nice too if you want to show leading zeros)
Thanks guys, these are the tips I'm looking for.
...dividing the number of minutes elapsed by the percent change is my task - "int" is the key this time
It doesnt work for greater than 24 hours
It returns 1:30 for 25.5 hours. It should have returned 25:30
Ideally I would right function as
=QUOTIENT(A1,1)&":"&MOD(A1,1)*60
Sorry, replied to wrong comment....

Clever use of MOD here to extract the decimal part of a number. Divide a number containing a decimal by 1 and return the remainder. Humm. Very clever.
Thanks very much, extremely useful !
