So how was your Christmas / New Year break? We had a quiet Christmas. Then we hiked a few mountains and camped in bush for few days. New Year was quiet too (as most of the family & friends are in India, while we are in NZ). As usual, we cooked and ate delicious food, had a few drinks and spent time playing cards, building stuff with Lego and drawing silly portraits of each other. I even squeezed in a bit of cycling.
Let’s talk about the untrimmable spaces.
We all know that TRIM() removes extra spaces from the beginning, ending and middle of a text.
So for example, if A1 has ” something and one more ”
TRIM(A1)
will give “something and one more”
We can use CLEAN() function to remove non-printable characters (like the ASCII codes 0 to 31). Of course, SPACE is technically a printable character, so CLEAN() won’t remove spaces.
The untrimmable spaces…?
The other day Sreekanth emailed me a sample of data and asked, “how do I remove the spaces in this list and convert them to numbers?”
Naturally I tried to TRIM().
But the data won’t budge. See below.
Hmm, let’s investigate why.
By using CODE(LEFT(B4,1)), we can check the code for the very first character in the value ” 4,124,500.00 ”
It is 160.
Hmm, 160, where have I met you before?
Poking in the Insert > Symbol tells us that 160 is the no break space. What an appropriate name that is.
In fact no break space is HTML character ie spaces printed on a web page. (Just to be clear not every space on a web page is char 160, but sometimes you have instead of SPACE.)
So how to remove the no break spaces?
Simple, we use SUBSTITUTE().
The formula =SUBSTITUTE(B4,CHAR(160),””) removes all the CHAR(160)s from B4.
But we want the number…
We can add one extra step to the above SUBSTITUTE() formula to convert text in B4 to number.
The below formula does the trick.
=SUBSTITUTE(SUBSTITUTE(B4,CHAR(160),””),”-“,””)+0
It replaces all CHAR(160)s and -s with blanks and then adds 0 to the resulting text thus forcing Excel to convert text to number. Bingo.
So there you go. For every byte of dirty data that sneaks in to Excel, there are eight ways to fight it out, at least.

If all this space business sounds like rocket science, then check out the example workbook to understand the formulas better.
How do you remove untrimmable spaces?
If it is a one time job, I usually rely on Find Replace to get rid of any symbols, characters or phrases. But if I have lots of data or changing data, I use SUBSTITUTE, TRIM, CLEAN.
What about you? How do you remove untrimmable spaces? Please share your tips in the comments.

Noooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo!!
Whyyyyyyyy?
The idea is to tell how to make a bubble chart. I got an e-mail from a reader recently asking how the scatter bubble is made. So I thought a 15 second tutorial would be a good idea to show this.
Did that email go "Dear Chandoo, I know that you scorn bubble charts, but if I don't do one in Excel for my boss then he'll fire my sorry ass, and my children will have to be sold for medical experiments in order for me to be able to afford the upgrade path to Excel 2010"?
If so, fair enough...it's all in the greater good 😉
Chandoo,
I am using excel 2003 and it is not working. The x axis is not the one that I enter in x axis column. Please help! Thanks.
Sorry, after few attempts, I managed to get the right result. I shouldn't select the title (header) of the table and select only the data to produce the right bubble chart.
What's wrong with bubble charts? Is there a better method for displaying scatter plots with lots of overlapping data points? Don't tell me you'd rather jitter!
@Sanwijay: Cool.
@Precious Roy: There is nothing wrong with bubble charts. Infact, it is the only way to show 3 dimensional data (x,y and sizes) without confusing your audience. Jeff is worried that people might misuse the chart. As with any chart, bubbles also have a place and time for using them.
I recommend using bubble charts to show relative performance various products in several regions and similar situations.
Also, human eye is notorious in wrongly estimating the bubble sizes (as we have to measure areas). See http://chandoo.org/wp/2009/07/28/charting-lessons-from-optical-illusions/
We can partially improve bubble charts by adding data labels, but if you have too many bubbles, the labels will clutter the chart and make it look busy.
I can't seem to find a way to plot more than ten bubbles on a chart and need to know how to add more
@KW.. why would such a thing happen. I am sure you can add more bubbles that that. Can you tell us exactly what you are doing...
Example table:
A B C (size)
Me: 25 30 15%
Him: 30 22 11%
Her: 12 30 20%
I am trying to make a bubble chart where the Y axis is A, the X axis is B, and the size of the bubble is C. There should be only 3 bubbles. I keep ending up with six (with the labels being only "Me" and "Her"). My goal is to have three bubbles, one representing each person. Clearly I am doing something wrong. Can you help explain...?
Hi,
I wanted to add data labels to the bubbles. Each bubble represents a different company name. Excel allows me to add the size, legend, x axis values and y axis values. How do I add instead- Company A, B, C, D for the bubbles?
youon you have to choice every data for every company..
ex:create bubble for A company,after that click right> add data label> adjust data labels :format data labels and choose : series name.
i hop u will succeed .
[...] we create a bubble chart with 2 bubbles. 1 for the actual mustache & 1 for target [...]
If we want bubble size to be controlled by one column, but the bubble labels to be controlled by another column, how can this be achieved?
many thanks!!!!
