  • 1. Copy cell to another as a comment
    I import external data and I would like to take text in a cell and add it to another cell as a comment. I have a long list of part numbers and some have sizes. I would like to take the sizes and add them as comments to the part numbers. Not all part numbers have sizes so I only want the ones with data in the cell. Any Ideas?
  • 2. To long formula for excel
    Like to find an answer too a long calculation in one cell, but the formule become to long just before I'm finish. A loop would have done it but I have no skills for to make it. what can I do to get around it? have tryied in many ways but excel do not let me get an answer to this. What can I do? Formula goes like this: =MMULT(MINVERSE(MMULT(TRANSPOSE OFFSET($L$80;DAG;0;Nobs;aksjer):OFFSET($L$80;DAG;0;Nobs;aksjer)-TRANSPOSE(MMULT(TRANSPOSE OFFSET($L$80;DAG;K$78;Nobs;aksjer):OFFSET($L$80;DAG;K$78;Nobs;aksjer));R80:R109)/Nobs)) OFFSET($L$80;DAG;0;Nobs;aksjer):OFFSET($L$80;DAG;0;Nobs;aksjer)-TRANSPOSE(MMULT(TRANSPOSE OFFSET($L$80;DAG;K$78;Nobs;aksjer):OFFSET($L$80;DAG;K$78;Nobs;aksjer));R80:R109)/Nobs))/(Nobs-1)); MMULT(TRANSPOSE OFFSET($L$80;DAG;K$78;Nobs;aksjer):OFFSET($L$80;DAG;K$78;Nobs;aksjer));R80:R109)/Nobs-U101)/ SUM(MMULT(MINVERSE(MMULT(TRANSPOSE OFFSET($L$80;DAG;0;Nobs;aksjer):OFFSET($L$80;DAG;0;Nobs;aksjer)-TRANSPOSE(MMULT(TRANSPOSE OFFSET($L$80;DAG;K$78;Nobs;aksjer):OFFSET($L$80;DAG;K$78;Nobs;aksjer));R80:R109)/Nobs)) OFFSET($L$80;DAG;0;Nobs;aksjer):OFFSET($L$80;DAG;0;Nobs;aksjer)-TRANSPOSE(MMULT(TRANSPOSE OFFSET($L$80;DAG;K$78;Nobs;aksjer):OFFSET($L$80;DAG;K$78;Nobs;aksjer));R80:R109)/Nobs))/(Nobs-1)); MMULT(TRANSPOSE OFFSET($L$80;DAG;K$78;Nobs;aksjer):OFFSET($L$80;DAG;K$78;Nobs;aksjer));R80:R109)/Nobs-U101))
  • 3. EXCEL GURU WANTED - Time calculations
    Problem is when taking a time-start cell from a time-end and applying a rate to the hours I get a different value from doing a simple calculation. ie simple calculation is 1.17 hours @ 130/hour = 152.10 Using times as Start Cell E2 = 13:00 & Cell D2 End 14:10 Calculating as: ((E2-INT(E2))*24)-((D2-INT(D2))*24) results as 1.17 Difference is 0.43? I have tried other calculations e.g. hour(d2) + minute(d2)/60) etc I am quite baffled can anyone help! If this 1.17 is used in the calculation the result is 151.67
  • 4. Frequency and If with multiple Columns
    Jym -- It sounds like you are trying to create a histogram, or at least the data to support one. Excel has a histogram method. If you've already installed it, it will be under >Tools>Data Analysis. If you haven't installed the data analysis tools it won't be there, but it's easy to install. Just go to >Tools>Addins, and click on 'Data Analysis' tools. (Don't click the 'Data Analysis - VBA', that's used for programming...). Then the histogram is available. You'll be able to make the table and/or chart, depending on what options you select.

I need to find the Average from Column A - but Reference Column B

Postby QkFNNzE4 » Wed, 16 Mar 2005 23:23:05 GMT

Column A has a Range of Dollar Values ($0 - $100,000).  Column B has a Range 
of numbers from 0 to 100.  

I want to return an average of the Dollar Values in column A but only using 
the Dollar Values that have a corresponding number in column B between the 
range of 0 to 10.

Hi

one method
=SUMIF(B2:B27,"<="&10,A2:A27)/COUNTIF(B2:B27,"<="&10)

as long as you don't have any negative numbers in B

Cheers

You could use the array formula:

=AVERAGE(IF((B1:B10>=0)*(B1:B10<=10),A1:A10))

In order to work, you must press ctrl + shift + enter 
after copying in the formula. An alternative would be:

=SUM(A:A,-SUMIF(B:B,{"<0",">10"},A:A))/SUM(COUNT(B:B),-
COUNTIF(B:B,{"<0",">10"}))

The advantage of the 2nd formula is that it is *not* an 
array formula and you can reference entire columns.

4.Need Macro to Find Column Heading -- if none, then insert new column

Using Excel 2002 to manipulate an XML file and save as XLS file which
will be linked as a table to Microsoft Access.  The issue is that the
XML file only shows table headings (i.e., column headings in Excel) if
there is data.  If no data, then no heading.

Need a macro that will do the following:
1. Find column heading (e.g. "Scheduled Review Date") if exists, then
end the if statement.

2. If heading does not exist, then insert new column and label column
as "Scheduled Review Date".

Thanks for your help.

5.Need to match 2 columns, if a match found add info from 2nd column

I'm comparing 2 lists of serial numbers.  The first list is smaller.  The 2nd 
list is more extensive and contains information in 3 more columns that needs 
to be added to the 1st list.

Example:

12345678        X          12345677
                                12345678   Mr Joe Bloggs    Feb 08     拢1500
12345679         X         12345679   Mr Fred Smith   Apr 08      拢600
12345681         X         12345680
12345682         X         12345681   Mrs Jane Doe     Apr 08      拢750

If the number exists in both columns, I need the remaining info (name, date, 
amount etc) to be inserted at X.

Please can someone help?
