VBA To Read Text Formula And Related Constants And Insert As Formula Into Cell

Jul 30, 2014

I have a situation where I have to curve fit data, this can lead to different formulas being used with varying constants.

Is it possible to pickup a TEXT based formula and related constants from other cells, and then place this into another cell as a functioning formula. For Example

Cell A1 contains the formula as a text string whether it be y=a+bx+cx^2, or y=a+b/x, etc
Cells A2:A6 contain the individual constants, a, b, c, etc

I would then want the VBA to read the text based formula and put it into an output cell as a functioning excel formulae.g

In cell B10: =a+b*A10+c*A10^2

I understand picking the constants up and putting the formula should not be too much of an issue, however trying to insert the variable form of the curve fit is the part that I am struggling with, and am unsure if possible.

1. search A1:AZ1 to find the cell that has the text "VBA Test" in the cell. There could be other text in the cell as well - this is not an exact match - but these two words are the common text.

I'm attempting to create a formula that will find the name associated with a value, and return that name on the same column as that value in a later equation.

OK OK to illustrate it a little better:

There are three people: Bill, Ted, and Andy. Each one is ranked in Points, so my table looks like this:

A B

1 Bill 10 2 Ted 20 3 Andy 30

Later on, I want to rank the individuals based on their score, using a formula. Right now, I can rank the scores based using LARGE(B1:B3,1), then LARGE(B1:B3,2), and lastly LARGE(B1:B3,3). That ranks the numbers in descending columns. However, I want the information to automatically populate the name associated with that particular point total. So, I want the system to know that B1 is Bill's score, and rank it, in descending order, later on in the spreadsheet, with Bill's name.

All I want to do is insert a formula into a text box. This thread answers the exact same question but I don't understand how to highlight the text box as an object... [URL]....

I have some data in the form of text w/ 8 letters. I'd like to insert a hyphen after the third character. Is this possible using a formula to populate an entire field? Example:

I have Combobox on sheet which is filled with list of time intervals (text). If I select item from combobox, I want this time interval to be splitted as text and fill one cell with start time, and other with end time - so that I could calculate time difference.

I guess this could be done by inserting formula in this start/end time cells, like :

[Code] .... and [Code] .....

I'm doing this to allow user for picking commonly used time intervals from Combobox, but also to enter other start/end time in cells for that. I cannot do that without VBA, but I don't know how to do It in VBA.

My time intervals in Combobox are all in this text format, example:

[Code] ....

How can I do that ? I can also post a sample worksheet !

I have a range of four courses (all child protection) that should be attended, some are eleanring, some local authority courses and staff should attend at least one but up to all four of them. Although they all fall under the question are they compliant or not (i.e.0 or 1)i do not want to count them all seperately. Is there any way I can look at all eight cells related to these courses and assess the latest date to assess if they are complinat (in date) or non compliant (out of date)?

I have attached the spreadsheet which I hope will clarify things

Assume cell A1 contains a date in DD-MMM-YYYY format. I would like to have a formula that looks in A1 and compares to the current date (TODAYS Date) and if the value in A1 is todays date or greater return "YES" and if not return "No".

(Thread: Max array with multiple columns) I got the following array formula:

{=MAX((A45:A47=A28)*(B45:D47))}

Here, where the value in A45:A47 is equal to A28, the maximum value is pulled from the same row, within cells B45:D47.

e.g.

A28 = Apples

A45 = Pears A46 = Apples A47 = Bananas

B46 = 10 C46 = 20 D46 = 23

The formula returns 23.

This is great. However, in order to control for a potential situation that will arise, I need to adjust this to find the first matching value within the data set. I do not know what the MAX should change to in order to find the first matching value.

Using the above example, if the data was now:

A45 = Apples A46 = Pears A47 = Apples

B46 = 10 C46 = 20 D46 = 23

How do you get the formula to return 10?

The position of "Apples" will change, hence the need for an array formula.

I would like to round the weight as per the matrix below. I have tried to put formulae in Column B but it is not yielding the desired result. Formulae in Column C which can convert the data to the desired result?

So the problem is that I have two workbooks: one has a set of identifying values which are a subset of one of the sets of values in the second and I need to match them up. In addition I need to take the values two columns to the right of the matched values in the second workbook and put them in the first.

I would like to copy a formula in a cell and then paste only the text of the formula, but I can't figure it out. Basically, I would like to avoid going into the cells and absolute referencing or hitting F2, then copying the text.

When I hit "Ctrl C" to copy the cell, then hit "Alt/E/S/F/Enter" to paste the formula, it is just like a regular copy/paste formula-wise in that the references move.

I'm trying to insert the following formula into cell AA11. For some reason I keep getting a 1004 Runtime Error. I'm assuming there is some type of syntax error. I'm not really sure what I'm doing wrong.

I am trying to use the code below to enter formulas into two different cells.

The first code "ActiveCell.FormulaR1C1 = "code" is running ok.

But the second one "ActiveCell.FormulaR1C1 = "=IF(IFERROR(IF(AND(1*LEFT(D2,2)>=61,1*LEFT(D2,2)<=65),VLOOKUP(AA2,'abc'!A:C,3,FALSE),""),"")="",D2,D2&AA2)" is getting error.

Sub Combine() Dim wbk1 As Workbook, wbk2 As Workbook

How can a formula perform the equivalent of the keyboard alt enter in a cell? ie Make =A1&A2 where A1 and A2 are cells containing text become a1text a2text in the new cell.

I want to make changes to a cell's formula when a combobox option is clicked, I can make the changes using sheet1.cells(x,y) = "=WHATEVER(bla,bla,false)" The problem is that when I run the program and make a change in the combobox, false is written as 'false' in the cells formula, which drives it into not working and displays ####### as the cells result.

I am making a deposit sheet schedule, which has 10-15 batches of deposits that are entered one after the other, vertically. Each deposit entry can be allocated to many different expense accounts, so a deposit will be 500 with 400 to rent, 50 utitilies, etc. So I need multiple summation rows

So, I want to add a sum row beneath each set of deposits.

My problem is that each deposit is a different amount of rows long.

I was thinking of doing something like this:

'totalRow() is each row where the summation formulas will go totalRow(0) is not an actual sum row, but tells me where the first row of data lies.

I don't know how to reference the ranges I want to sum, because I don't know how to increment the reference to the column (i.e. changing A to B to F to G, etc.) with the Range().Formula construct.

I was thinking of using R1C1 somehow but I'm not as familiar and I don't think you can use r1c1 & Range() at the same time.

i'm sure this can be done but i cant get an angle on the method. i want to use VBA to put a formula into cell G3 based on the users entry in cell D3 so, for example the user enters M in cell D3 and the VBA code puts the formula "if D3="M",A3,0"into cell G3

i know i could use a formula in the cell but i want it to work with multiple entries so i figure VBA is the way to go.

I want to insert a new row that contains the formulas of a fixed row (1:1). The inserted row is changeable and is determined by whichever is the current active cell.

Eg:

Active cell is something random like E16

I want to add a new row but don't want a blank row - rather want a row that contains the properties of 1:1

I am using a For Next statement that doesn't return the results for all the rows. The statement is as follows:

For Row = 1 To 100 If ActiveCell.Value = "CHANGE" Then ActiveCell. Offset(0, 2).Range("A1").Select ActiveCell.FormulaR1C1 = "=RIGHT(""0000""&RC[-1],20)" ActiveCell.Offset(1, 0).Range("A1").Select ElseIf ActiveCell.Value <> "CHANGE" Then ActiveCell.Offset(1, 0).Range("A1").Select Else: Range("A1").Select Exit For

End If Next

Range("A1").Select

I hope I did that according to the rules. It only returns the result in the first cell that does have a value of "CHANGE". It seem to be going through the entire range of cells, but I'm not getting any results.

I was wondering if it is possible to write a formula so that the below table can be read based on the input (in this case start month and cut-off month) and return the value from the table. I have also attached the excel with the data and some examples.

If I type the name Joe Bloggs How can I make whenever i type that name the computer knows to retreive a number or formula from a cell on another or same sheet.
