If IFERROR() were to be a person, I would hug her so hard that Jo (my wife) would get in to a cat fight with her. I know many a woman (and man) who get in to a fight with Excel formulas often. But thankfully, we avoid that as IFERROR is not a real person. It is, however a darned useful formula.
Since I cannot hug a formula anymore than I can get my son to sit tight, I will go ahead and sing an ode to her, in my style – by writing about how useful and powerful IFERROR formula is.
What is IFERROR() Formula & How does it work?
Introduced since Excel 2007, IFERROR() formula checks a formula (or expression) and returns the value of formula if there is no error, otherwise a custom formula.
For eg:
=IFERROR(1/0,"Try splitting an atom instead!")
will give the message Try splitting an atom instead! because the expression 1/0 returns an error (DIV/0 error)
Where as,
=IFERROR(0/1,"Try splitting an atom instead!")
will give the value 0 since 0 divided by 1 is 0.
How does IFERROR help me?
Archimedes once said, “Give me enough data and a spreadsheet, I can make any formula return an error.”
May be he was too confident, but errors are everywhere. And that is why IFERROR is useful. It provides an elegant and simple way to tackle the errors in your workbook.
Several common uses of IFERROR are,
- 1. While writing lookup formulas like VLOOKUP, INDEX+MATCH it is common to search for values that do not exist in your data. You can wrap such formulas in IFERROR for peace of mind.
Ex:=IFERROR(VLOOKUP(...),"Not found") - 2. While using reference formulas like INDEX, OFFSET, frequently, we try to fetch the data that is not in the list of values. This returns #REF errors. You can fix them with IFERROR easily.
Ex:=IFERROR(INDEX(...),"") - 3. While using arithmetic, numeric expressions, usually we end up dividing by 0. You can fix such things by using IFERROR.
Ex:=IFERROR(AVERAGE(...),"0")— Returns 0 when the list has zero values.
Things to keep in mind while IFERRORing:
Please note that IFERROR is oblivious to the type of error. That means, no matter what the error is (DIV/0, #NAME, #N/A, #REF… etc.), IFERROR treats all of them equally and shows the same value. In other words, IFERROR is like “Catch all” in programming world.
How to handle errors if you are using Excel 2003 or below?
In earlier versions of Excel, we have a formula called as ISERROR() that can check an expression or formula for error and return TRUE if so. This formula is not same as IFERROR, but we can use it along with IF() formula to get the same result. For eg.
=IF(ISERROR(VLOOKUP(...)),"Not found",VLOOKUP(...))
works same as, =IFERROR(VLOOKUP(...),"Not found")
Notice that the ISERROR approach evaluates VLOOKUP formula twice!.
Do you IFERROR?
To err is human, to IFERROR is awesome.
Ever since discovering the IFERROR feature in Excel 2007, I have been using it so often. I use it to keep my output sheets clean and my formulas simple.
What about you? Do you use IFERROR? What is your experience like? Would you also give it a hug? If so, would your spouse get in to a cat fight with it? If so can you post some pics of it on our facebook page?
Please share your experiences and tips on using IFERROR() thru comments.

Quite a nice and helpful article. I am sure excel is one of the most used application across many many big companies. And your info on project status update using excel would surely be usefull. Keep up the good work on this blog site. Also to share there are some open source flash-based graphing and charting solution which caould also be used on any project..
http://askwiki.blogspot.com/2009/07/how-to-create-quality-charts-using.html
@Alex, Izabel .. thank you 🙂
@Miguel: Thank you. Your dashboard looks very good. It is inclined towards the budget and finances of the project. I have kept those aspects out of this series. May be I will revisit the financial aspect of projects at a later point.
@Rishil: Thank you. Yes, you can create flash based charts (or even simple image based charts) and embed them in a project dashboard that can be published to the team using intranet (like sharepoint). This is how large companies usually do it. Thanks for sharing the Askwiki article.
Great looking dashboard!! Do you have a version for the Mac versions of Office available?
Thanks
Chandoo,
this is great piece of collating info.I liked it and shall try using it in office.
Thanks for the all hard work behind this.
Chandoo,
Kudos. This is really as simple as it gets for laymen. We did this sort of stuff in Consulting - but this can now become really simple for people. Will have my team look at this! Great work.
thanks,

Have you done anywork on a Project Portfolio Dashboard template?
@Bw... Thanks for getting a copy of the templates. 🙂 I have worked on few assignments where we built such templates. But these are similar to other regular dashboard templates. I will share some of these ideas in a later post someday. Meanwhile if you have any ideas on how to structure project portfolio dashboard, let me know using comments or email.

Thanks fro the great ideas! To get a sense of the layout and design of a Dashboard more geared toward Cost and Schedule anaysis, check out the example Dashboard at http://www.ProjectDashboards.com which was built entirely in excel.
hey,
i just need a simple Chart where by i can show some of the projects by % wise. no dates required.
1st column Project name and 2nd column will be status (filled with %). can you pls help me out.
Thanks.
@DS... if you have excel 2007, you can use data bars in conditional formatting for this purpose.
Hi Chandoo - this series is an excellent resource and tutorial, thank you for sharing.
When I sat down to consider what my dashboard should look like, one of the most important features for me is to be able to maintain version control and to show simply on what version is on display.
Apart from the naming convention of the file name, is there a good way to do this within a dashboard? I'd be interested to hear your thoughts!
@Larph: Welcome 🙂
> You can do version control thru Macros (but always remember that your audience can disable macros)
> Another option is to use a static time stamp / version number in the title page of dashboard that you update manually whenever you make changes to the file
> In excel 2010, you can keep track of file versions from File menu. This can be used to select a previous version of dashboard.
> Best option is to use a version control system like SVN or upload files to Sharepoint or something like that. This will take care of versioning for you (although it is a bit technical and dashboard audience may have difficulty figuring the versions out).
> The easiest option is to use filenames and the CELL() formula to get the version number (or date) from the filename so you can show it on the dashboard.
Hi Chandoo... I'm following you from Brazil...
I would like to thank you for the tips about excel, mainly with dashboards ... It helped me a lot …
Take care...

Hi Chandoo, do you have an equivalent Project Management Dashboard / Project Status Report for MS Office 2010?
As a Microsoft trainer I'm interested in your choice of Excel for project management. I'm assuming that you've tried Microsoft Project and have decided not to use it? We get folks on our MS Project courses who've tried to use Excel for PM purposes and none of them have made such an impressive project plan, but I wonder is it worth all the effort?
This looks very interesting. How may I be a part of this
Does this template work in Google Spreadsheets?
Many thanks for sharing your expertise with us. Keep up the good work 🙂
Heya i'm for the first time here. I came across this board and I to find It really helpful & it helped me out a lot. I am hoping to offer one thing again and aid others like you helped me.
Hi Chandoo,
Your PM dashboards impressed me so much that I've downloaded the Portfolio and Project Management package. All of the documents look very professional.
I was going through the Portfolio dashboard and I had a question.
When I enter in additional holidays they are highlighted in the gantt chart. Is it possible so that the name of the holiday shows up in the highlighted area of the gantt chart.
Thanks

can you confirm that the downloads will work on a mac - excel for mac v14.3.6

Made a slight variation on the schedule sheet,
1. Add a date column for start
2. In week column cell use =weeknum() and link to date cell
3. Hide week column
When you enter in a date for each task the week number is populated accordingly
simple but more effective, you can also dynamically link the date cell to your MSP project file for even more automation!!
I purchased a copy of the project management dashboard excel file. I misplaced the password to unlock the file and make modification. Can you please resend the password.

This is my first time pay a visit at here and i am actually happy to read all at alone place.
I am interested in your dashboard; downloaded the locked version, unable to use it...do you have a user guide that is available that I can see and use on the locked version?
