Speed Improvement - Macro Extract Higher/lower Values And Note Time Differences
Jul 8, 2009I have a macro that needs a major improvement in performance. I have a Quad Core 2.67GHz single processor computer and with the current logic it calculates 20 values per minute. I have data sets that can be up to 400,000 data points, which means it will take 333 hours. The attached Sample file has over 9000 point. For this data set it takes 7.5 hours.
The core logic of the macro is to extract what I call “Break Point” into column M and “Time Difference” between the Break Points to column O.
I got the code from this forum (thank you DonkeyOte) and made some modifications. The modified logic does the following:
1) The user inputs the starting cell. In the Sample I use G200.
2) From cell defined in button, It moves down one cell in that column and compares that value to the original cell.
If the value is greater than original cell then there are 2 possible outcomes:
a) move down 1 cell in column and if that value is less than original cell, then extract that value and copy that value to the column M (Break Point value) and copy the Time Difference Value to column O. “Time Difference” is calculated as the difference between the 2 point breaks in Column A. In this case I’ve hardcoded 0.003472222 to get 5 minutes which matches up with each incremental time in column A, but I would like the Macro to automatically calculate that by the difference between Column A values.
b) move down 1 cell in column and if that value is greater than original cell, then move down again, until find lesser value than original cell. Once we find value less than original cell, extract value and copy value to column M and copy the Time Difference Value to column O.
Once lesser value has been copied to new cell, logic is now:
a) move down 1 cell in column and if that value is greater than original cell, then extract that value and copy that value one cell to column M and copy the Time Difference Value to column O.
b) move down 1 cell in column and if that value is less than original cell, then move up again, until find greater value than original cell. Once we find value greater than original cell, extract value and copy value one cell to column M and copy the Time Difference Value to column O.
At any point in the process if we find a value equal to the starting cell, we ignore it and the logic continues. The logic continues flip flopping like this to the last value of column G.
OR
Here's the logic now in reverse I need:
If after moving down 1 cell of original cell, the value is less than original cell then logic has the following 2 outcomes:
a) move down 1 cell in column and if that value is greater than original cell, then extract that value and copy that value one cell to column M and copy the Time Difference Value to column O..
b) move down 1 cell in column and if that value less than original cell, then move up again, until find greater value than original cell. Once we find value greater than original cell, extract value and copy value one cell to column M and copy the Time Difference Value to column O.
Once greater value has been copied to new cell, logic is now:
a) move down 1 cell in column and if that value is less than original cell, then extract that value and copy that value one cell to column M and copy the Time Difference Value to column O.
b) move down 1 cell in column and if that value is greater than original cell, then move up again, until find lesser value than original cell. Once we find value lesser than original cell, extract value and copy value one cell to column M and copy the Time Difference Value to column O.
Again, at any point in the process if we find a value equal to the starting cell, we ignore it and the logic continues. The logic continues flip flopping like this to the last value of column.
Once all the Break Points and Time Difference between Break Points are extracted for each value in column G, the AVERAGE, STDEV and MAX values of column O are calculated in column Q, R and S.
There is a loop that controls the execution of the core logic until the last value in column G. In the macro I’ve hardcoded last row being 9171, but I’d like the Macro to figure out what the last row is automatically.
I know this description is a bit long but I’ve worked for many hours on getting it work properly. I just need some help to make it run much faster. I hope someone can help me out on this. I have the right logic, just need the speed now and I really can’t figure it out.
Attached is a sample files demonstrating showing how the logic to flips back and forth as moving down the column starting in cell G200.
The sample shows the results first 4 loops (Rows 200 to 203). The values in M and O are the results of the fourth loop.
Again, assistance is very much appreciated because I've taken this as far as I can with my limited experience.
EDIT - I can embed the Macro, but it'll probably much easier to actually see it in the sample file.

Aug 5, 2012Have Excel 2003. I have
List of email addresses in column a
List of email addresses in column b
** I would like a formula that will take all the values in column A and compare it to the entire list of entries in column B.
Would like it to show in Column C any entries in Column A that ARE NOT in the entire column B.
*Would like it to repeat for entries that are in Column B, but not in Column A and show in D.
*Then would like a count of the differences for each column (that is pretty easy).
It needs to look at the entire list of entries in the column as these will be email addresses. We want to know what is missing from Column A that is not in Column B and what is missing from B that is not in A.
Extract Text From Given Point In Text String When Data Points Do Not Share Given
Jul 9, 2014I have a set of task descriptions that I am attempting to trend on. Some of these (Column B) have the customer's name added to the description; others do not. I need to be able to make a list of task names (ColumnA), removing the name from the text string.
The formula I am using is [=LEFT(B3,FIND("for",B3)-2)].
The problem I am having is when the description does not contain the "for" built into the formula, I get "VALUE" error. What adjustment can I make to the formula to pull over the Description if the "for" does not appear in the text string?
Extract Multiple Text Strings From A Long Text String
Sep 4, 2009An original text string entry appearing in an Excel cell would be:
"N7C Neuroprotective J5Z Antiviral, other M2Z Antiarthritic, other J5A Antiviral, anti-HIV"
I need to extract N7C, J5Z, M2Z and J5A from this string and list these alphanumeric values in separate cells adjacent to the original text string. The challenge is that these alphanumeric references may appear in different positions within the original string with no fixed value e.g. a "," separating them. The alphanumeric references may also be 3 or 4 characters in length and there may be different numbers of alphanumeric references in the original string.
Another example would be (very different from the first):
"T2Z Recombinant, other K5B Radio-chemoprotective J3Z Antibacterial, other D3A Vulnerary A10C Symptomatic antidiabetic K6Z Anticancer, other R8A Antiasthma B6A Septic shock treatment I1Z Immunostimulant, other S1Z Ophthalmological R8B Antiallergic, non-asthma M1A1 Anti-inflammatory"
You can see that in this further example "A10C" & "M1A1" are 4 character alphanumeric strings wheras the others feature 3 characters.

Extract Text After Last Specified Character
Aug 15, 2007I have a cell in my worksheet with a fully qualified filename like 'D:abcDefGHIJklxyz123.app
I would like to extract only the xyz123.app. Obviously, the number of characters is going to vary based on the filename. The find and search functions appear to locate the cell but not the substring in the text. The right and left appear to work based on number of characters and in my case these are varying. Also, there does not appear to be any function that can do a search a string from right to left.
