Get rid of that ugly formatting with two simple tricks

We are on a tiki tour around NZ. So far we have been to Taupo & Rotorua. And we are doing what you do when you are on a holiday – being lazy, going on walks, swimming in lakes, eating copious amounts of food and getting lost. Of course, all this means, I have very little time to access to internet & my blog. So the updates will be slow for next two weeks. Here is a quick tip (well, two of them) to keep you busy and awesome.

Untrimmable Spaces – Excel Formula

Published on Jan 12, 2017 in Excel Howtos, Learn Excel
Untrimmable Spaces – Excel Formula

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 above.

Hmm, let’s investigate why.

Fix Incorrect Percentages with this Paste-Special Trick

Sometimes we get values in our Excel sheets in such a way that the % sign is omitted. So instead of the value being 23%, it is 23. Now, you can very easily correct this by editing the cell and adding a % sign at the end. But what if you have 100s of rows of data. You can’t do this to every cell. (You can not just format the cells to % format either, excel shows 23 as 2300% then). There must be some simple and intuitive solution for this … umm.
