Excel formula fixed cell address


How to insert a formula with a fixed cell address? Absolute referencing will come to the rescue.

Absolute reference in Excel is prefix with a dollar ($) sign.

$A$1: This means that Column "A" and Row "1" will not change when copied to another cell.

Example:

      =SUM(A$1,$A2,$A$1)


The above formula when copied from one cell to another cell, $A$1 will remain the same.

While A$1,$A2 will change its location when copied to another cell.

 A$1: This means that column "A" will change while row location (which is number 1) will not change when copied.

 So this absolute reference will change like D$1, G$1 or E$1 depends on the location. So number "1" value will never change.

 $A1: The column "A" will not change when copied from one cell to another cell, while the row value which is number "1" will change.


So the above absolute reference will change like $A3, $A10, $A12 etc., Column "A" will be constant while the row changes.


So, in a layman point of view; to make the address absolute then prefix it with "$" dollar sign and anything beside the dollar sign will not change.


To understand it clearly, try this example:

 In column A, of the excel sheet input these values from A1 to A6:

123

456

789

1122

1455

1788


On cell "D1" type this formula: =SUM(A$1,$A2,$A$3)

 Copy the formula to cell E6.

 And copy also a formula to cell F7.

 

After copying the formula to above cells, the formula will be like this:

 Cell E6 will have this formula: =SUM(B$1,$A7,$A$3)


Cell F7 will have this formula: =SUM(C$1,$A8,$A$3)


Cell E6 change the formula =SUM(A$1,$A2,$A$3)   to =SUM(B$1,$A7,$A$3



Cell F7 change the formula =SUM(A$1,$A2,$A$3)   to =SUM(C$1,$A8,$A$3)


If the formula is copied to Column C or B it will result to an error.

 It will result to error because where the formula is copied, absolute reference treat it as the point of reference.


That's why formula in Column "E" change to "B" and Column "F" change to "C". Since the point of reference is Column D and absolute referencing treat it as "Column A".



For the row in absolute referencing it looks like that counting starts at number "2".


So if this formula =SUM(A$1,$A2,$A$3) is copied to cell E1.


The formula will be changed to: =SUM(B$1,$A2,$A$3)


Excel is just a giant tool, but it's quite good if you know how to tune it.


Cheers, till next time.

Copy a single file using robocopy

Copy a single file using robocopy from a local folder to a shared folder on the network.
A simple rule of thumb before any disaster strike, don't interchange the source and the destination.

If source and destination is mistakenly reverse, files might get overwritten. To avoid any loss of data do a test with a dummy file to ensure things work perfectly.
Robocopy [source][destination]   [file to be copied]
robocopy c:\local_c_folder  \\PC_network\shared_folder   file_to_be_copied_xx.txt
The command will be completed successfully provided the network access right has no issues.

Robocopy works quite good on large files. A simple copy or xcopy command will also work but the speed might vary.

Robocopy is free it can be accessed from command line. No need to install the resource kit tool if the operating system is Windows 7 or newer version.

Copy files with selected file extension using PowerShell and Robocopy:

$extension = ('.pdf', '.jpg', '.txt')
gci d:\WorkFolde…

WMIC get computer name

WMIC get computer model, manufacturer, computer name and  username.
WMIC is a command-line tool and that can generate information about computer model, its manufacturer, its username and other informations depending on the parameters provided.
Why would you need a command line tool if there’s a GUI to check?
If you have 20 or 100 computers, or even more. It’s quite a big task just checking the GUI to check the computer model and username.
If you have remote computers, you need to delegate someone in the remote office or location to check.
Or you can just write a batch file or script to automate the task.
Here’s the code below on how get computer model, manufacturer and the username.
Open an elevated command prompt and type:
wmic computersystem get "Model","Manufacturer", "Name", "UserName"
Just copy and paste the code above, the word “computersystem” does not need to be change to a computer name.
A sample output below will be generated if the co…
