In the first part on our Modeling Best Practices series, we learned 5 best practices to follow. This article shows how to automatically implement the best practices using macros.

Best Practice Modeling using Excel - Make these 5 changes to your Excel models today

Quick Re-cap on Modeling Best Practices

Make cell content and cell purpose visually identifiable at all times

In the first article I highlighted the fact that the content and purpose of every cell should be easily identifiable to the user at all times.

At a basic level we can identify two basic cell types:

Type Background Font Protection
Assumption or constant White Blue No
Output Grey Black Yes

 

Best Practice formatting made easy

In order to make the application of Best Practice formatting quicker and easier I have created three simple macros. These macros use Excel’s Go To Special function and then some simple formatting to the active sheet.

Demo of the macros

Please watch this 5 minute demo to understand how the macros work.

[Click here to watch the video]

Overview of best practice macros

Auto_Format:  automatically formats cells depending on their type:

  • Number constants (i.e. input cells) are white background, blue font & unprotected
  • Non number constants (e.g. formulae) are grey background, black text & protected

Constants_Format:  formats selected cells as white background, blue text & unprotected

Formula_Format: formats selected cells as grey background, black text & protected

And a couple of extras:

Simple_Audit:  A Simple Audit Macro that uses the go to special function to select and highlight specific cell types. This is the macro from the Managing Spreadsheet Risk article.

Clear_format: formats all cells as white background, black text & protected

A word of warning: These macros apply formatting to your spreadsheets. This formatting cannot be undone.

File to download

Since formatting steps vary for Excel 2003 & 2007, we have 2 versions of the files. Please download the appropriate file below:

Excel 2007 and above version

Excel 2003 & below version

These files have the macros embedded in them. You will need to move these macros into your personal workbook. Help on this.

Once in your personal workbook you can then add these to your QAT, or Ribbon.

Conclusion

Have a play with the macros on the example workbook and then, once you are happy with how to use them, you can start applying best practice formatting at the click of a button.

Let us know how you are implementing these best practices and your suggestions using comments.

    Afternoon,

    I have one similar calander that I added conditional formatting to so that I could highlight any planned factory holidays. I think i "borrowed" the formula from another calander so I won't post it here.

    I also added week numbers to it using the formula =WEEKNUM(MAX(C6:I6)) Where C6:I6 is the range of dates in that give week. It works fine on most of the months but return strange values on other months (Week 6 in October?) I can't see any logic behind why it does this.
    Any suggestions for an alternative formula to give the week numbers?

    Regards,

    William

    Hi Chandoo,
    I've added a new feature on your spreadsheet.
    This control can be useful for all the sheets where you need to check dates.

    Cheers

    Hi Chandoo,

    Nice calendar.
    Till now whichever calendar I saw in Excel, it contained only the outline sheet.
    Good to see monthly views and the mini view too.
    Liked the mini view much. 🙂

    -Nimesh

  5. Chandoo says:

    @William: This weeknum may be because the input dates to max are not properly formatting as excel dates.

    Good tip on the conditional formatting and holidays btw...

    @Migueal: Now that is super awesome. This is the reason why I love to blog. Readers will always one up me with such cool alternatives. Thank you for sharing this with us.

    @Nimesh: You are welcome 🙂

  6. Shish says:

    is it possible to get the Notes section on the outline page to display the notes added to the month page for a specific date?

    So if you add thing for January 2nd, and then select January 2nd those notes appear on the outline page

  7. Chandoo says:

    @Shish... You can do that using some formula magic. I would not recommend pushing excel to that as outlook / google calendar / icalc etc. do exactly that much more elegantly.

  8. Jörg says:

    Happy christmas to all of you!
    This is really awesome. The nicest calender I've seen for Excel. I also like Miguels version of the sheet.

    Just one "feature" is missing to me. As I live in Germany - where weeks start on Monday - I'd like to change this. Could someone please give me a hint how to do this?

    Thanks in advance

    Jörg

    Hi Chandoo, I’ve added some new features on your spreadsheet with your permission.

    Check it here:
    http://cid-6b219f16da7128e3.skydrive.live.com/self.aspx/.Public/Calendar%5E_Pedro.xlsm

    Miguel, this calendar is translated to Spanish language.

    Jörg, this new approach allows us to start weeks on Monday.

    Also it's possible to start weeks on Sunday if you enable Excel macros and push the arrows.
    Best Regards,
    Pedro.

    @Pedro.. superb stuff.. thanks for sharing the file with all of us.

  11. Pedro says:

    Hi Chandoo, for dates before March 1, 1900 our calendars are wrong.
    In Microsoft Excel, DATE, EOMONTH, WEEKDAY functions return an incorrect result between Monday, January 1, 1900 and Wednesday, February 28, 1900.
    See this page: http://support.microsoft.com/kb/214326/en-us/
    Microsoft Excel incorrectly assumes that the year 1900 is a leap year in all Excel versions.
    That's the reason why our calendar versions only work from March, 1, 1900 until December, 31, 9999.
    Your comments are welcome.
    Pedro.

  12. Chandoo says:

    @Pedro.. Thanks for pointing that out. wow... This reminds me of the Joel Spolsky's first BillG review - http://www.joelonsoftware.com/items/2006/06/16.html (read it, I am sure you would love it.) when Bill out of blue asks about date time implementations for VBA (which Joel is the program manager for...)

    Thanks for sharing the URL too... Here is a specially made, chocolate sprinkled, extra fluffy donut for you 🙂

  13. Pedro says:

    Hi Chandoo, thanks a lot for the donut but I prefer it without chocolate!

    Always it's good to know a little history of Excel.
    The Joel Spolsky’s last BillG Excel review was about the "Hall of Tortured Souls"
    (See this Excel 95 Easter Egg here: http://www.eeggs.com/items/719.html)

    Do not miss the humor!

  14. Pedro says:

    Please, I need help!
    I like all calendar from Pedro, thank you for them. Let me show my problem:

    I have 2 excel cells (for example AE12 and AE13) which mean the starting and the ending date of my duty. I need a macro to insert sheets with label YEAR. MONTH (for example 2010. August or similar) with the proper datas between the two dates. Is it possible?

    Thank you for reading me and sorry about my terribel english! 🙂

  17. Peter says:

    Hello Pedro,

    Thanks so much for the modified calendar template. I love the extra functionality you added. Is there any way you could upload an unlocked version? I wanted to change some of the comments and data validation so I could use it for one of my applications.

    As for feedback on potential improvements, with all the additions you made the file runs pretty slow. I'm sure this has to do with all the interconnectivity between the various tabs, but if there is a way to use less memory via more efficient formulas or something else I think this would make it easier to use. I have a brand new computer and with it running alone the response was pretty slow. One of the changes I'm making is changing the order of the months to match my company's fiscal year, so maybe something to automate a change like that could be useful.

    Cheers,

    Peter

  18. Pedro Wave says:

    Peter, my calendars are unlocked but you need Excel 2007 and 2010 versions to open them.

    Now I return with a new Programmable Task Calendar:

    Wath an introductory video here:

    This new calendar allows to select the start month to match the school and fiscal year.

    This is great stuff Chandoo and company

    Wanted to know if someone had built something similar

    I need to store one Excel Sheet on this calendar that has all the holidays

    US Holidays appear in RED
    UK Holidays appear in Blue
    Meetings appear in Green
    Submissions appear in Orange

    Is there a way I can store the list in a separate worksheet and all the calendars get updated with this?

    Thanks
