Update: As of Sept 3rd, 2010, this code or approach no longer works. Twitter has taken themselves too seriously to disable a working protocol in lieu of complicated oAuth. I am keeping the post intact for amusement and knowledge of xmlhttp works.
Twitter is fun. You can stay in touch with your friends and followers, 140 characters at a time.
Out of curiosity I opened the twitter api documentation today to see if it is possible to build an excel based desktop client to post messages to twitter.
It turns out that, doing this using twitter api is relatively simple. So I went ahead and built an excel sheet using which you can post messages to your twitter account. Interested? Read on
Create a new MS Excel file and make a data entry form like this
You can insert the button using form controls. Go to menu > view > toolbars and select “forms”.
Now select the button control and draw it on your sheet.
Excel will show a dailog asking which macro to run when that button is pressed. Enter the name as “tweetThis” or something cool.
Make sure you adjust the text color of password field same as background. That way your colleague (say hello to her from PHD) cannot look over your shoulder and know your twitter password.
PS: if you are using Excel 2007, form controls will be available in “Developer” tab of ribbon. If you don’t see developer tab, you must turn it on from “excel options”. Press office button and select excel options. I guess the option will be in “Advanced” area.
Create named ranges for your data
(this step is not mandatory)
We need just 3 fields of data to post a message to your twitter account. User name, Password and Message . Select each of the 3 cells and create named ranges for them. Name them something meaningful like “tusername”, “tpasswd” and “tmessage”. To create a name for selected cell, just press menu > insert > name > define (press the create name button in excel 2007)
Now, the fun part, writing macro code to post your message to twitter
The actual code is no geek stuff. We will use XMLHTTP object to do our work.
What is xmlhttp? it is the same object your browser uses to dynamically receive and send data from websites. It is the stuff behind all those cool AJAX powered sites.
First, right click on the “tweet” button you have created and select assign macro option. In the window it would show your macroname (tweetThis). Select it and click on edit button. This will open VBA Editor. Don’t freak out. 🙂
Our code needs to do the following stuff:
- Create an xmlhttp object
- Use twitter API’s post method and post the message
- Get the status and display it in debug window (just so that we would know if something went wrong)
- Close the xmlhttp object
I have written the below code, but I am sure you can write your own looking at how simple it is.
Sub tweetThis() Dim xml, tUsername, tPassword, tStatus, tResult Set xml = CreateObject("MSXML2.XMLHTTP") 'get the username entered by you in named range tusername tUsername = Range("tusername") 'get the password entered by you innamed rangetpasswd tPassword = Range("tpasswd") 'get the message entered by you innamed range tmessage tStatus = Range("tmessage")xml.Open "POST", "http://" & tUsername & ":" & tPassword & "@twitter.com/statuses/update.xml?status=" & tStatus, False xml.setRequestHeader "Content-Type", "content=text/html; charset=iso-8859-1" xml.Send tResult = xml.responsetext 'you can view Twitter’s response in debug window Debug.Print tResult Set xml = Nothing End Sub
Finally, enter your user name and password and a test message and test your code
If everything is fine, you should be able to tweet from that spreadsheet. Here is a sample message if you don’t know what to tweet:
Wow, http://chandoo.org/wp just posted a cool new way to make your own twitter client
You can easily extend this code to check someones status message, DM or message someone or analyze twitter stream. For processing twitter data you can use DOM parser objects from VBA.
Download Twitter from Excel Application and Play around with the code
Go ahead and download the twitter from excel app and learn by opening the code etc.

For those willing to go VBA, XL can do far more w/Gantt Charts. Compare to PapaGantt. https://sites.google.com/site/beyondexcel/project-updates/papagantt-thebigdaddyofxlganttcharts
While making PapaGantt was neither quick nor easy, using PapaGantt is both, not just for displaying Gantts, but for scheduling tasks as well.
is it possible to get a xls(m) file ?
instead of a zip-file with .xml-files ?
i cannot open it with excel :/

@Stef@n
Try saving the file and then open from Excel as opposed to opening directly from the post
Also try this link: http://img.chandoo.org/pm/quick-gantt-chart-template.xlsx
Thanks very much for this workbook idea.
To slightly up-scale functionality I added:
1. conditional format for when the cell value =2 to be red which could be used for critical path or other activity highlighting needs (milestones perhaps)
2. conditional format for when the cell value =c to be green which could be used for showing activity progress
3. conditional format for the same range where formula =DATE(YEAR(D$5),MONTH(D$5),DAY(D$5))=TODAY() and set custom to ;;; and cell fill colour to a light blue. This will highlight today down the whole table to allow quick assessment of activity progress to plan. Anything not green upto where the date indicator is shows activity is behind the plan. Opposite for tasks ahead of the plan.
(There is probably a better way to get the same result but this works for now. If there is please post for us to share.)
Hope this made enough sense.
Also, thanks Craig for the link. I'll have a better look soon.
Regards,
Darren
Hey Chandoo,
I actually made one of these for a friend of mine but added an extra level of automation.
Rather than putting in 1 on all the dates the activity occurs, I added a column for start and end date of each project. Then I used formula along the lines of :
=IF(AND(DateAtTop >= Start Date, DateAtTop <= End Date),1,"")
Then used the same conditional formatting where 1 was coloured.
I thought this was a nice touch, especially if a project lasts for many days.
Let me know what you think 😉
Lucas
P.S. First time I've posted here, love your work btw!
Hi Lucas... welcome to the comments and thanks for your first of many comments.
I like the idea. In fact, it was one of the first Excel tricks I ever learned (to use conditional formatting to automate things like this). See this (written almost 6 years ago)
http://chandoo.org/wp/2008/03/13/want-to-be-an-excel-conditional-formatting-rock-star-read-this/
and scroll-down to the tip on gantt charts. 🙂
I liked this approach and tried adding it into the Conditional format via Formula = statement. It workd fine with just the AND statement but then I realised you need the "1"'s to calcluate the duration.
I then put the whole IF statemnt in but it hasnt worked. Any thoughts?

Hi Lucas and Darren,
I tried the conditional formatting but I really don't succeed in getting the solution. Do you have a template of this?
Thanks in advance

Excellent, thanks for this tip and expample.
I had a monthly reporting template very similar to this, but was done in excel which needed more manual inputs.
I used your exmaple and updated my monthly group reporting plan.
I further devided the day into 4 quarters to make it easy for us to followup on different tasks.
Now, I just have to update the start date, and everything gets udpated by itself in fraction of a second.
Thanks once again. love your daily udpates.
Wow.. glad to hear that.
Hi Prahlad,
Can you share ur template even i am looking for similar kind of template .where i want day duration ,split in hrs and each task effort represented in hr spent by each resource .
Thanks
savi
Hi Chandoo,
Can you guide on preparing an indian version of the captioned sheet. We have saturdays working :-(, and only one day weekly off on sunday.
Regards-Prajay
Hi Chandoo,very useful post.i need gantt chart for inventory module.
[…] Quick and easy Gantt chart using Excel […]
Hi.
Really usefull post. I would like to know if i can also include weekends.
Thank you
Hi Chandoo, thank you for the great job, I was wondering if you can customize this sheet for Inventory planning purposes?!
thank you indeed
This was so helpful. ive been through about 10 different tutorial type things and this has to be the best so far, helped me out a great deal. and now my boss is happy i can make gantt charts!
thanks
This's a great post, thanks for sharing
Hi Chandoo,
Thanks for the excel tutorial. I wanted to make a simple modification, however it will cause issues with the duration part. I created another rule/cell marked 2. For my project I want to show a projected timeline and then an actual timeline. The issue is that the duration is being logged for when I enter 2, which I want to be projected and not actual. Will you please assist in letting me know how I can create a duration for both project and actual on the same line?
Thank you,
Steven
Showing vertical line between every week is very useful for me, I used to do it manually. Thanks so much!!
But how about, my gantt chart included Saturday & Sunday, and I want to show the vertical line after Sunday, could any expert teach me how to fix it. Thanks again.
This was so helpful - thank you! I had a bit of trouble with the end of the week conditional formatting over-writing the filled cells but switching the order of the rules sorted it out. Needed to put together a gantt chart quickly for an important bid at short notice and this was just the job - thanks for taking the time to post it. Much appreciated.
This is the first time I'm reading a tutorial that actually makes sense 🙂 This is absolutely great, with only one minor issue I can't seem to figure out on my own. How do I include weekends in (or instead of) the Workday formula? Thank you!
[…] This template I made myself but I inspired from Chandoo.org. […]
Hi,
Sometimes I must work at weekends - it is possible to modify the dates so that you can include Sat + Sun as well?
Thanks,
H
Nice gantt chart template chandoo, simple but useful
Thank you so much for this excellent guide! I have adapted this to show scheduled activities at multiple project sites weekly over the course of the year, including active and proposed work. With just a tiny bit of tweaking to your tutorial, I was able to create a chart that suited my needs perfectly!
Thank you very much for idea sharing .very innovative workday formula is showing 5 days but i want 6 days , is there any other option plz reply..
i got it friends..
=WORKDAY.INTL(F4,1,11)
hhhhhh
@Somnath
I also like the structure using =WORKDAY.INTL(F4,1,"0000001")
where each day is a 0 or 1
Hi thanks a lot for the tuto!! It helped me a lot!!
But can you tell me how can I add a vertical line representing today on it?
@Cynthia
Open the template
Select D7:DS26
Goto Conditional formatting
New Rule
Use a Formula
=D$5=today()
then set the format as a Red Right Hand Border only
Apply
Do not select stop here for the rule
Hi Chandoo,
I purchased your Project Management templates a month ago and have not had the chance to thank you for the great templates. Thank you!!!!! It has saved me a lot of time creating and re creating templates. Unfortunately, I had to do a lot of customization but it's not that bad. I am now in the process of customizing my GANTT which my boss thinks is too granular. He doesn't want to see a weekly grant. Only the months should be showing. I have researched and researched but to no avail. Do you have any examples I can look at?
Hi Chandoo,
thanks so much for all your tips on Gantt Table.
I'm actually building one at the moment and want to use the conditional formatting. However, I always get into trouble with that when I have to add new lines. I don't know the final size of my table yet and I eventually also want other people to be able to work with it.
Conditional formatting tends to "split up" into various "applies to" ranges when you insert a new row or copy and past values from somewhere.
I'm sure you've come across this issue already... So far I couldn't find a feasible solution to this. I was wondering if you had an idea / suggestion for me?
Thanks so much!!!
Nadine
