Regex To Extract Cell References From Excel Formula To ArrayList?
Jan 5, 2009
Has anyone created a regex that matches each of the cell references in a given Excel formula? I'm trying to extract a list of cell references into an ArrayList from a provided Excel formula. Ideally, the ArrayList would also preserve any cross-tab or cross-workbook reference information. The key is for the regex to be compatible with any potential Excel formula, as the formula will change with each use.This seems to capture cross-workbook references:
'[.+'!($?[A-Z]+$?[0-9]+(:$?[A-Z]+$?[0-9]+))

I am trying to parse the parameters of Excel formulas like "=a(b)", "=a(b,c)", "=a(b,c,d)". I'd like extract the function name "a" and the parameters "b", "c" and "d".
There are loads of examples on SO to parse HTML and so forth, but none specifically for parentheses.
So far, I've got this "=(.+)(([^,)]*)(,[^,)]*)*)" but when I parse "=a(b,c,d)" it puts "a" in match(1), "b" in match(2) and ",d" in match(3). So "c" is lost and the comma before the "d" is a pain.
How can I parse a string like this with an arbitrary number of parameters, ideally dropping the commas?
The ability to parse "=a(b(c),d(e(f)))" would be great...
Edit: I know that a parser is the correct solution and I have used Devin Cook's excellent Gold Parser with great results before.
However, the particular case I'm facing is to extract the arguments from a known Excel formula. Specifically, if the formula contains the string "=Travel(", I know that it will have 4 arguments and if they don't parse it's not a problem. This is simply a "nice to have" function which can fail occasionally without it being an issue.
regex for "=a(b,c,d)", "=a(b,c,d,e)", etc., with the constraint that there will be no nested parentheses or commas?

I have a string which is like this - MVAL("A","01-01-1900")+MVAL(B,"01-01-1900")+MVAL("C")+MVAL(D). Now I want to extract B AND D out of this using regex because it is the first parameter and it has no quotes around it in both the overloaded version of the functions. Secondly because MVAL function is an overloaded function with two versions like MVAL("A") and MVAL(B,"01-01-1900") how will I find which version of the function is being used.
I'm using System.Text.RegularExpressions.Regex method.

With vb.net I would like to select 4 cells in Excel and then pass those cell values along with 1 button tag to a formula in Excel.I press a button with a month, say "May" as text. I want to grab a cell in Excel labeled "May1t" the value of which is the number of hours until may. This is the code I'm using.
xlsWB.Worksheets(2).Range(Month1 & "1t").Value I am able to set a variable with this as the value but,
I want to pass this cell (which will be updating as the time counts down) and 3 other similarly specified cells along with the button tag to an Excel formula.I have something like this:
Private Sub F_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles F.Click
xlsWB.Worksheets(4).Range("B2").Formula = "=MyFunction()"
xlsWB.Worksheets(1).Range(Month1 & "1t").Select()
End Sub
The formula takes the parameters in the order: MyFunction(Cell,Tag,Cell,Cell,Cell).

I'm inserting data into excel sheets and after i fill each sheet I want to sum a column so select the data and add a formula to a cell. However when the sheet is opened the cell contains the formula as text instead of the sumation value. I tired several ways but here are a few different meathods that both end up with the same undesired result.
Code:
'Meathod 1
oSheet.Range("H2:H" & (dtEntries.Rows.Count + 2).ToString).Select()
oSheet.Range("H" & (dtEntries.Rows.Count + 2).ToString).FormulaR1C1= "=SUM(R[-" & (dtEntries.Rows.Count).ToString & "]C:R[-1]C)"

Im trying to extract ALL urls from a webpage in between two sets of strings.
I have the code to extract all links, but I am
href="http://www.blah.com/yadayada?tf=info"
Using regex; I want to grab everything between href=" and the quotation mark at the end .
This was a snipit I found that works for extracting in between 'href="' and </a>
HTML
Regex.Matches(data, "href=""(.*?)"".*?>(.*?)</a>")
I learn best by example, and I tried piecing it together by comparing the regex match above, to a URL in between hreft" and </a> - but I couldnt do it. Ive been working on this project for a while, and im getting tired.

I have a formula, found in an Excel sheet that I have to convert to vb.net...I can't figure it out, eventhough it's seems a quite easy formula to me.the formula is: Mod(X + Int(Y/100000);20)In fact if I render some values...and use the Mod function in Excel or in VB.NET it gives me other results.

I want to write a formula to SUM from column B4 to M4, this should be done using vb.net programming.
I tried using the following stuff:
oXLWsheet.Range(4, 14).Formula = "=SUM(oXLWsheet!$B$4:M$4)"
"=SUM(B4:M4)"
"=SUM(B4,C4,D4,E4,F4,G4,H4,I4,J4,K4,L4,M4)"
Nothing is working for me. I'm getting the following error when I run the code:
"Exception from HRESULT: 0x800A03EC".

I have been stumped on this for about 3 weeks now. In the beginning me and my partner have been trying to hit this at the internal angle. only problem is different html tables are constructed different than others. We are needing to extract from multiple pages and sites so we know that Regex will be the best solution. We can use the same script for everything. This is my first time working with Regex, I got it actually extracting the very first ip[proxy]. I have no idea why it isn't extracting every one on the page. I also have to add the . in between each each octave of the ip. That is weird because I have it in the Regexpession to find the .'s.What I'm Needing is for this to basically scan the whole page and grab all the ipsorts and add them to a listbox.Here is my
Dim request As HttpWebRequest = Nothing
Dim response As HttpWebResponse = Nothing

I want to calculate the difference between 1st Value (B2) and last Value (last populated row in column B)
Edited :
Using formula : =B2-B6 is not what's required. (I want diff in Cell C2)
I want when the user enters the value in B7 it automatically shows the difference between B2 and B7, when he populates B8 then it shows the diff between B2 and B8 and so on.. I don't want some direct method to do this in Excel and not by iterating all values to check the last value.

I'm attempting to copy cells, one at a time, from an Excel 2003 (or 2007) spreadsheet to a Word 2003 (or 2007) table. I'd like the code to be version-agnostic, and so am using late binding. The formatting of the contents of the Excel cell, such as color, underline, strike-through, needs to be preserved. My approach is to use a Word doc as a template. It has a table at the top which I can copy to the end of the doc, add rows as needed, and fill in the word table cells with the data from the excel spreadsheet. Unfortunately, all the formatting disappears. All I get is the text itself.
