Dynamic Correlation Calculation

I have an excel worksheet that adds two other worksheets in a data
triangle. I copied it to create a new data set and used find &
replace to change the worksheet references to the new ones.

The cells still contain the result of the old formula referring to the
previous worksheets. The only way I can get the formula to return the
correct result is to edit (F2) each cell and press enter. Calc now
(F9) does nothing.

I've seen this before, but this time, I need to calculate many
thousands of cells and don't have time for this workaround.

Any ideas?

Thanks.

Since there isn't a ISDATE function in excel.

The following can be used to simulate the same, and avoid having to achieve the same with VBA's IsDate function:

STEPS:
1- Format the column (ex A) as text

2- Formula to check for valid dates:
=ISERROR(DATEVALUE(A1))

From limited experience I know that excel calculates dates via serial numbers.

I have formulas to add a number of days to a cell containing an entered date and display the resulting new date (ie. 03/01/2011 (c34)+11 = 03/12/2011)

I am seeking to leave resulting formula cell blank until a date is entered in the input cell. Currently when the input cell is empty the formula cell obviously displays 1/11/1900 using the above example.

What conditional format would achieve leaving the formula cell blank until date data in entered into the source cell?

Hopefully a simpler question for your experience level than mine.

I am using the following formula to calculate the number of days between a date and the current date: =DATEDIF(A1,TODAY(),"d") What do I add to the formula to leave cell blank if no date is entered in the cell for calculation.

I often use if statements to return empty cells, for example:

=IF(a1=0,"ERROR","")

The trailing "" returns an empty cell. The problem is, it is not TRULY empty. If I fill that formula down, I cannot, for example, jump from one "ERROR" cell to the next by hitting Ctrl arrow-down because it seems to think that these empty cells have contents.

Is there a way to designate, in such a formula as above, to return a TRULY empty cell?

Thanks

I have a workbook that has compliance dates in columns "F","G" and "H" from row 7. What I need is when the date in either column comes within 30 days to auto send an email, address in column "A", recipients name in column "B". and then place todays date in column 'P". ALso need to send a follow up email when either date comes within 7days and then place todays date in column "Q". If there is a date in column "P" then don't send email. If there is a date in column "Q" then don't send follow up. Can this be done without the users intervention and each time the workbook is opened.
Thanks in advance for any assistance.

Hello,

I have two columns of data: column A contains the date and time in the form dd/mm/yyyy. Column B contains a number value. All the times are in order, so column A looks like:

01/01/2007
02/01/2007
03/01/2007

I have data from 2007 to 2010. I need to calculate an average daily value (in column B) for each month, and display it in column C. So, for January, I need to calculate the average of 31 days, February, 28 days, etc.

Is there a function I can use to do this? I've been trying the AVERAGEIF formula but can't get it to work. Any ideas would be much appreciated!

Many thanks,
Caitlin

In excel, I am trying to find a formula or funtion so that when I enter a
date (1/10/05) in cell A1 for example, then B1 automatically changes to
1/11/05, C1 to 1/12/05, etc. Can anyone help? Thanks!!

Hello All

I wonder if you could help with this one, I have a list of data like this (no spaces or other characters)

JN551122B

What I need to do is split each of the characters in to its own cell

if JN551122B was in cell A1 I'd want to return:

B2 C2 D2 E2 F2 G2 H2 I2 J2
J N 5 5 1 1 2 2 B

The nearest I have got is the right function, but it brings over the preceeding characters, and I need each character in its own cell. Hopefully I could copy/paste a formula and change the reference for each cell value, i.e. 1 would return J, 2 = N, 3 = 5, 4 = 5 etc.

Thanks for your help!

Hi there,

How i can convert Hijra (Islamic) Dates into Gregorian?

a formula or VB

any help

Entering time values in custom format [h]:mm:ss
Cells accept hours over 23,
Adding cells in column returns correct total time.
Have not found a way to multiply these cells by a $ hourly rate.
So use HOUR(cell ref) and MINUTE(cell ref) to capture values in referenced
cell - then use these values to calculate total payment for $rate per hour.
However, the HOUR(cell ref) formula returns the hours in excess of 24 when
the cell contains an hour value in excess of 23 (ie 27 hours returns 3).

How I Can Maintain The Stock Register On Excel Sheet By Date Wise ?

But I do not want to insert any sheet for different dates & also the format will not be copied & paste in the same sheet. Just at the place of Date the date will be changed & the datas will be entered manually for each day.

In future, when I shall put the date, the datas will show that particular date's datas only.

Can anyone help me ?

I have entered a vlookup formula in a cell and it returns the correct value from the other worksheet. However when I copy the formula down it keeps returning the exact same value as the first cell. If I enter a formula in each individual cell it returns the correct value. Its driving me crazy ! I woyld be glad of any advice

Many Thanks

I need a formula to calculate Turn Around Time. Find below the sample data and details for your reference.

Received Date & Time: 10/29/2010 3:27:00 PM
Completed Date & Time: 11/1/2010 3:57:32 AM
Business Hours: 08:00 AM to 05:00 PM
Non Business hours: 05:00 PM to 08:00 AM
Weekdays : Monday to Friday
Weekends: Saturday & Sunday

If I calculate TAT for this time period it should show me 1 hour 33 minutes, why because business hours are closing by 5:00 PM on 10/29 so it should not calculate duration after 5:00 PM to until 08:00 AM on next day, however 10/29 is Friday so formula should calculate the duration from 10/29 Friday 3:37 PM to 10/29 5:00 PM and again it should calculate from 8:00 AM on 11/01 Monday and formula should skip Saturday & Sunday.

In this scenario I have completed the task before 8:00 AM on 11/01 so it should show duration of 1hour 33 minutes.

Please let me know if you need any more details

I found this solution for "drop down list with hyperlink" but it did not work.

Perhaps a better solution is to use a workaround that relies on the HYPERLINK function to refer to whatever is selected in the drop-down list. For instance, if you have your data validation drop-down list in cell A1, then you might put the following formula in cell B1:

=HYPERLINK(A1, "Goto Link")

The solution directly above provides exactly what I am looking for
in the field where I write the formula, but it fails to hyperlink.
I have created a drop down list and linked each one of them to a
specific worksheet. When I select them individually they link to
appropriate worksheet. But when I select them in the drop down
list I receive the following error when I select the Hyperlink in
cell B1 as directed above.

"Cannot open the specified file"

Any thoughts?
