Calculate hours between two cells

February 27, 2017 ANmar

We needed that several times in the past Then I found it in an old file in my laptop, thought to share it for others to help So, when A1 has the start time, B1 has the end time Time different in one day will be from formula =IF(OR(A1=””,B1=””),””,ABS((HOUR(A1)+MINUTE(A1)/60)-(HOUR(B1)+MINUTE(B1)/60))&” hrs”) I added to prevent…

Fx to cut long column into two columns

Convert one long column into two
This set of formulas will get the items after row 45 (for example) from column A into the column B starting from B1 to have two 45-rows next to each other instead of one 90-rows column

This was the answer for this question

Show two columns in one page as four columns using functions only. This will help you to show the next x number of rows for a certain column to the next of the first one to reduce the number of pages to print.

Multiple Dual-Validations

February 9, 2012 ANmar No Comments

It is to demonstrate how to do multiple validations in the same sheet, or as we want to call it

Mutliple-dual-validations

that depend on each other.

Checking out sheet “Data”, you can tell that Validations on column B is for the heads (Main categories), and on column D is for the sub category of the main that used in column B in that row.

Creating something like this basically falls in three parts

Part1: is the Names you need to define, so after we create the table found “Data” sheet …..

We need to set two names, one for the left-top cell for that table (used as reference) and another name with formula:

Dynamic selection list

Using Index and CountA Formulas, Names and Forms > ListBox to have a list with connected formulas

Can also be used as form to read from a large table in another sheet

After creating two names, one is “Months” having:

=OFFSET(Sheet1!$B$5,0,0,COUNTA(Sheet1!$B:$B)-2,1)

And the other one is “Month_All” having:

=OFFSET(Sheet1!$B$5,0,0,COUNTA(Sheet1!$B:$B)-2,3)

Draw a listbox using “Developer toolbar”, then make its input list as “Months” name we did above, then use these formulas:

Creating a Data Validation based on another Data Validation

Meaning that when you select from a drop down from the first the second will be filled with the list that is corresponding to it.

You need to create two names (Formula > Name Manager), one has this formula

=OFFSET(Sheet1!$A$2,0,1,1,COUNTA(Sheet1!$2:$2))

The other one has this
