I have a given length of steel bar...Example(550 feet)
I have various cut lengths that I can pick from...
14'-10".....13'- 9".. 12'-8"........(up to 6 different lengths)

I need to know the best combination of lengths to cut the long bar into to have minimal scrap left when we get to the end of the 550 feet.....

Cut as many of the longest cut lengths possiable.....Cut as few of the shortest cut lengths possiable

Due to the fact that I will have to convert this to a PLC application when completed, I want to find a mathmatical way to do this inside excel and not use the "solver"....Assuming that I/we can come up with an equation to do this .....
Any and all advice/help would be appricated.....

Imagine a whole box of lengths of aluminium sections for making windows.

To make those windows I need to cut these lengths into smaller sizes.

I need to do this economically.

How can I use Excel to help me make this a reality.

Firstly you would take a big size out of it and then another size out of the offcut piece.

And then another size out of the offcut left over.

I need to know how many full stock lengths (6500) long it will take to cut all the pieces listed above.

Is it possible?

You need to take into account the quantity of each size and fit it all in together for the most optimal outcome.

See attached example of possible layout.

Hi Excel experts,
I am working on a worksheet, and would like to have an entire row transferred to another worksheet based upon a certain cell's value.

Having searched through the many solved threads on this site, I attempted to customize some of the code to my worksheet. Not being proficient in Macro/VBA, I failed. I figured I would ask for help, and see if anyone can provide what I am looking for.

Basically, I am attempting to construct a "work in process" file, and would like all completed work to be deleted from the work in process sheet, and transferred to a sheet that contains a running list of all work completed.

Attached is an example of what I am working on. I would like Column Q (Status) to determine if a row can be moved to a sheet that contains the list of all work completed, and eliminated from the original sheet. Once Status is updated to "Complete", it would be helpful to be able to run a macro/click a button that would perform the transfer.

Can anyone assist?

Thanks!

Hello,

I am new to using Excel and I am not very computer literate. I am looking for some help with a spreadsheet I am making. Here is the problem:

I have a column of 14 numbers in cells A1 to A14. If all of these values are less than 2%, I would like a "Pass" to display in cell B1. If any of these values are greater than 2% I would like a "Fail" to display in cell B1.

I have got a formula that works for a single cell but I can't figure out how to get it to apply to more than one cell. For example, I have entered =IF(A1<2,"Pass","Fail") in cell B1. Now if the value I enter in A1 is less than 2, it shows a "Pass", and if the value in A1 is greater than 2 it shows a "Fail" in cell B1. How can I get this to apply to all of the cells from A1 to A14?

If somebody could help me out that would be great.

Thanks,
Randy

Hey

I have three columns containing last name values from 3 different sources that I've brought into one sheet. I am trying to find a way to compare all three values to establish if they are the same.

Of the three values there is no master, Each value may be different. So essentially it would be like doing =IF(a1=a2=a3,"match", "nomatch")
But of course this isn't possible.

I don't care about obtaining detail about which value matches which. I just need true or false response as to whether all three values are the same or not.

Thanks for any help anyone can provide.

I have searched and read all the help files. I find the properties of
an object, I see how I can "lock", "size and move with cells" or "not
move with cells". No matter what I select, the object moves off the
screen, when the user, scrolls to the right of the spreadsheet.

Is there a way to lock the position, let's say , in the upper right
corner and have it stay there?

This would be quite useful for an EXIT button, that I have created,
that will close the program without saving (it's a read-only file.)

Thanks to all the wonderful people here that have been so helpful and
give us their valuable insight and time.

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 cells in a column, some colored yellow, some not. I am trying to use
the SUMIF function to sum only the cells in the range that are colored. Can
this be done? Can I enter something in the "criteria" part of the formula
that can do this?

=SUMIF(D3:D13,"criteria",D3:D13)

I also tried to use the CELL function's color feature, but I couldn't get it
to work right. I don't know how to get Excel to recognize if a cell is
colored in a formula.
=CELL("color",cell)

It might just be that I don't know what this means in Help:

"color" --> 1 if the cell is formatted in color for negative values;
otherwise returns 0 (zero).

Can anyone help?



I'm trying to come up with a solution to calculate the man hours and days worked over multiple sheets.

I have a file that has 8 sheets. the first seven sheets are the days of the week and the 8th sheet is where I want to calculate the hours.

The days of the week consists of "Name" "Date" Hours"

The 8th sheet consists of "Name", "Days of the week in their own column (7 columns in total)", "Total Hours" and "Total Days Worked"

Now... each day is always a different group and what I'm hoping for is to create a formula that can grab each name with their hours and throw them into the 8th sheet. So when the end of the week is done I have all the Employees weekly hours and days worked all finished.

I hope this makes sense. This file is to track about 100 employees that are on a rotational work schedule.

I have attached a sample file.

Thanks in advance for your help.


Hello.

I have two huge excel files, with many rows and columns, they "should" look the same.

But I need to find out if anything has been added or removed from the second one compared to the first one.

Which is the easiest way to accomplish this?

Searched this forum and Google but couldn't find what i was looking for.

Thanks in advance!


Hi all -

Im very familiar with how to write a macro to automatically autofilter a list based upon a Cell Value (i.e. Range =(A1)...etc.).... but what I cannot figure out how to correctly write is a way to have Excel automatically autofilter a list for any row that CONTAINS the Cell Value, instead of just the exact value.

Cell Value = "birds"
Example -- I need to filter every row so that I see every row that CONTAINS "birds" in the character-string, not just the row that = "birds".

a) is this possible?

If not, I'd like to know also so I can stop attempting to guess (-;
Thanks!!!

How do I set the formula if

if F1...I1 <10 = Pass, >=10 Fail (and highlighted red), and any cell between F1....I1 is empty = blank


is it possible to put two formulasinto one cell?

On the attached timesheet there are columns IN, OUT, IN,OUT
The lunch time is worked out by deducting 'C8 from C9' and this works fine when all 'IN, OUT' cells are filled in but for some reason when just the first two cells are filled in it gives a -12 hour answer.

looking at cell 'C11 ' in the attached worksheet, I currently have the formula
=IF(C13=0,","SUM(C9-C8)) The reason for this is to make it look tidy by having blank cells until a calculation is needed,, My problem is, If someone just comes in for the morning one day for instance 8am to 12 noon then they won't have lunch, but C11 will show -12:00
Can I put another formula into C11 to tell it not to deduct C8 from C9 until a time is put into C9.
The following is the sort of thing (many variations) I have been trying but because I'm hopeless at formulas I'm not having any success
Thanks

=IF(C13=0,","SUM(C9-C8))OR,IF(C9,ISBLANK,"",SUM(C9-C8)


Is it possible to apply a filter to multiple sheets within the same Excel workbook, using the same filter criteria?

For example, suppose you have tables of data on 3 different tabs, all having the same headings. Suppose one of the headings is "gender". If you apply a filter to the table on Sheet 1, to only show the rows containing the word "female", is it possible to have the tables on Sheets 2 and 3 automatically update to only show the "female" rows? Or would you have to manually update the filter criteria in Sheets 2 and 3?

I hope this makes sense. Thank you in advance for any help.


How do I get the colors to change automatically when I use a drop down list.
Per say here is what I am trying to do

If a certain "word" is used from the drop down list I want the background of
that cell to change its color to "green." And if later I change the "word" to
another from the drop down list, it will change it's color to a specified
color.

The drop down list that I use was created from cells that have the colors
already in the "word", but I do not know how to make the list show the colors
so it puts the word & color automatically in the drop down list to the cell
with the drop down (if that makes any sense).

If there is a way, please spell it out simple enough for me to understand,
as I don't know fully the capabilities of formulas or vba.



Is there an Excel guru that can help with this - its related to "drop down menus"


I have 2 colombs of data.

AT the bottom of the first, I have created a drop down menu using the "data validation" feature in excel.

At the bottom of the second colomb, I have used an "IF" function that returns a result, which depends on what value is chosen from the drop down menu in colomb 1

The problem I have is that I want the TRUE result from the IF function to be another drop down menu, being the data in colomb 2.


How do you write an IF function where the TRUE result is a drop down menu??
I tried to create a drop down menu of colomb2 elsewhere in the spread sheet, and used that cells location as the TRUE value, but this didn't work either...

ANy suggestions??


In Excel there is a difference between cells that are blank (= "") and that are empty. You can make blank cells empty by selecting them and pressing the delete key, but I need a fast way to do this on all blank cells in a large worksheet. The only way I have found is with a VBA macro that loops through every cell, tests for '.Value = "" ' and then uses the '.Clear()' function, but doing this on 30 columns x 10000 rows is far too slow. Any solutions?

(The reason I need to do this is for importing into Access, the database treats empty cells as NULL which is what I want. Blank (but not empty) cells screw the import process up.)


Hi Everyone,
I have searched online and in help but can't seem to find the best solution...

I have values like 00904BB303D6 that need to become: 00:90:4B:B3:03:D6 (the value is always 12 digits, and the : needs to appear every two digits.) Is there a formula that can easily do this for me? Your suggestions are greatly appreciated!

Thanks in advance!!!!

I have a spreadsheet set up with an employees information, including the start date. After each year that the employee is working, he gets bumped up on the pay scale. For this reason, I only need to know how many years the employee has been working, rounded down to the nearest year.

This is what I have so far (hire date is in column B):

=((TODAY()-B4)/365)&" YEARS"

This function gives me a number with many decimal places.

I tried:

=ROUNDDOWN((TODAY()-B4)/365),0)&" YEARS"

It tells me I have too few arguments. Please help!


I have been using Excel (XP) to make a text chart for several months. Some of
my text entries are rather lengthy. The past two weeks these lengthy entries
are showing up as pound signs (#########) when I click off the cell. I know
the text will fit in the cell, and the problem isn't solved by making the
cell bigger or using a little bit less text. I have the cells formatted as
"text" and "wrap to fit". I have printed the pages and the printed version
also has pound signs. I just want my text to show up!



Hello, what I would like to do is take a portion of a sheet..... So the cells I want to mirror are in the proposal sheet cells B32 x F51. And then mirror the exact duplicate copy to another sheet. The other sheet should have those same values at A20 X G39. What I am trying to do is have a sheet that has skus, prices, and so forth and then when I add,delete, merge, color, or do anything to the cell on the "proposal creation" sheet I want it to mirror only a specific cells to another sheet that is "salesman copy" that we will print to clients. So this way ont he proposal copy a salesman can insert rows or even change the color of the cells and then have it mirror exactly the same on the "salesman copy" which is what we will print for clients. Thank you.
