Hello I am trying to categorize quantitative data into 4 categories: Low, Medium, High, Very High.
=IF(0.35<G2<0.554,"Low",IF(0.555<G2<0.699,"Medium",IF(0.7<G2<0.799,"High",IF(0.35<G2<0.8,"Very High"))))
Does anyone know why this keeps returning "False"?
Thank you
It's because =0.35<G1<0.554 does not make sense from Excel's point of view, Excel's logic would require to make it AND(0.35<G2,G2<0.554). Nested IFs are difficult to read and maintain, I would suggest using a look up table as per the example below:
This would be the correct syntax you're looking for. If you want multiple criteria you have to use the AND function and make single comparisons multiple times.
=IF(AND(0.35<G2,G2<0.554),"Low",IF(G2<0.699,"Medium",IF(G2<0.799,"High",IF(G2<0.8,"Very High"))))

I am trying to extract unique Article Numbers from a big database inside excel. It will go up to 15000-20000 unique article numbers. I have tried to use the code below to solve this, and it does work. But the document gets so slowed down by this and thus becomes a pain to work with. This will be used every day so at this pace it would be unbearable to work with. Do you know any good ways of speeding this up? Read smt about binary search, but I don't know how to implement that into the code I have down below. Any help is appreciated:)
=IFERROR(IF(LOOKUP(2;1/(COUNTIF($A$1:A1;Unique) =0);Unique)= 0; "";LOOKUP(2;1/(COUNTIF($A$1:A1;Unique) =0);Unique) );"")
//The unique is just a named range, so it doesn't have to handle the full 20000 rows at all times
Oh that would work. I can write some vba code to perform that action :) Ty very much
Hello i'm having problems with getting this to work. What i'm trying to do is when you insert a set of measurements i want excel to show the ( In this case products) which are closest to those measurements.
here is a picture:
The result i'm trying to reach is when you type in the measurements you get product(s) and the manufacturer which are closest to those measurements.
Any help is greatly appreciated.
In essence, what you are after is an index+match function. It will allow you to find a value in one list, given a corresponding variable. In this case, given a measurement, it will find a manufacturer and product combo in your list.
Your problem is that you will need to adapt your data to allow for this. For example, you need to decide whether you only want the closest match for measurements or if you need the closest match that is greater than the measurement you provide.
It is also possible that you'll need to split your measurement column into two different columns (unless all you need is the total area irrespective of individual lengths).
You could potentially avoid the index+match by using conditional formatting, but that would still require the data manipulation.
Given the information you provided, the answer will never be much more informative than this. But this should get you started and the following steps can be made easier with help from google.
Let me share the problem, where I am trying to decide the winner list comparing multiple parameters:
First of all, I need to compare the fault points. The less you have the better place you get. If the fault points are equal, then I need to compare the time. Comparing the time, the faster you performed the greater place you get (green column represents the right result).
I have used this formula:
=IF(AA16="";"";COUNTIF($Z$16:$Z$24;"<"&Z16)+1+SUMPRODUCT(--($Z$16:$Z$24=Z16);--($AA$16:$AA$24>AA16)))
However, I get a wrong comparison for the time parameter. My guess is that it is either a small issue I am having or the formula itself is completely wrong.
Thanks in advance.
Use this formula instead:
=RANK(Z16,Z$16:Z$24,1)+SUMPRODUCT((Z$16:Z$24=Z16)*(AA$16:AA$24<AA16))

Looks like this might be helpful. They have an example related to breaking ties that I think will work for your scenario.
Excel Functions: Rank
I would like to create a report that look like this picture below.
My data has around 500,000 cells (it will continue to grow larger)
Right now, I'm using countifs function from excel but it takes a very long time to calculate. (cannot turnoff automatic calculate)
The main value is collected as date and the range of date is about 3 years, so I have to put a lot of formula to cover all range of value.
result
The picture below is the datasource the top one cannot be changed. , while the bottom is the one I created by myself (can change). I use weeknum to change date to week number.
data
Are there any better formula or any ways to make this file faster? Every kinds of suggestions are welcome!
I was thinking about using Pivot Table, but I don't know how to make pivot table from this kind of datasource.
PS. VBA is the last option.

I will post this answer with the disclaimer that it is entirely dependent on the size of the data set. That turning on and off the auto calculate is the best way, but your question doesn't let me do that, so keep reading.
Your question made me curious, so I gave it a try and timed it. I essentially set up two columns of over 100,000 rand numbers choosing from 1-1000 and then tried to do a countif on the two columns if they were equal. I made a macro that I can run that turns off the autocalculate, inserts the start time, calculates, and then inserts the finish time. I highlighted in yellow the time difference.
First I tried your way, two criteria, countifs:
Then I tried to combine (concatenate) the two columns to see if I could make it easier by only having one countif criteria and data set. It doesn't. see result below:
Finally, realizing what was going on. I decided to make the criteria only match the FIRST value in the number to look for. I was essentially reducing the number of characters to check per cell. This had a positive result. See below:
Therefore my suggestion is to limit the length of the words you are comparing in anyway possible. You are mostly looking at dates, so you might have to get creative, but this seems to be the best way possible without going to manual calculation.
I have worked with Excel sheets of a similar size. Especially if you are using the data on a regular basis, I would heartily recommend switching to a proper database SQL based, Access, or whatever fits your purpose. I does wonders for the speed and also you won't run into the size limits of Excel. :-)
You can import the data you have now fairly easy.
I am happy as a clam with my postgresql db.
I´ve a very large file that I reduced as much as possible to 3 columns and 80k rows.
I need to perform a vlookup in order to bring values from column 1 or 2 match some other spreadsheets values.
The thing is Excel doesn´t seem to support such large searches, and it stops responding - the computer has 4GB and a Quad core, and not much more running at the same time.
As far as I understand, as I´m not looking for exact matches, I should not use match-index.
The only thing I thouhgt could help but not sure about that, is dividing the file in 2-4, and asking Excel many parallel searches instead of a big one. Could this work?
What else should I try?
Thanks!!!
Sort your data and use True as the 4th VLOOKUP argument. This makes VLOOKUP use binary search rather than linear search and is lightning fast.
If you need to handle missing data you will need to use the double VLOOKUP trick, see
