Each line is needed in a different cell. moving to the right, essentially in the same row of a multidemensional array.

Many of these files will be pulled in sequence.
 
If needed i can split this up into different questions, i just do not know how to do this.
If i am unclear, Please ask questions

if you have the filename then you can use a streamreader

string filename = "c:\example.txt";
 
        //METHOD 1, read the file line by line
        System.IO.StreamReader rdr = new System.IO.StreamReader(filename);
        while (!rdr.EndOfStream)
        {
            string line = rdr.ReadLine();
            //do something with the line
        }
        rdr.Close();
 
 
        //METHOD 2, read the entire file then use code to split it up
        System.IO.StreamReader rdr = new System.IO.StreamReader(filename);
        string allText = rdr.ReadToEnd();
        string[] lines = allText.Split('\n'); //<--split by newlines, but could also split by commas etc
        foreach (string line in lines)
        {
            //do something with the line
        }
        rdr.Close();

Once you have all the data that you have parsed out, you could use it to fill a datatable or write a .csv file (excel can read .csv files)


eg. if you wanted to put each line from the file into the next cell in excel

        System.Text.StringBuilder b = new System.Text.StringBuilder();
 
        System.IO.StreamReader rdr = new System.IO.StreamReader(filename);
        string allText = rdr.ReadToEnd();
        string[] lines = allText.Split('\n'); //<--split by newlines, but could also split by commas etc
        foreach (string line in lines)
        {
            b.Append("\""); //add opening quote around the value 
            b.Append(line);
            b.Append("\","); //add closing quote around the value, the comme 
        }
        rdr.Close();
 
        //at this point the stringbulider contains your one-line csv
       
        string csv = b.ToString(); // put the csv into a variable if you want
 
        //or write the csv out to a file
        System.IO.StreamWriter wr = new System.IO.StreamWriter("c:\destination.csv", false);
        wr.Write(b.ToString());
        wr.Close();

After reading the file you can apply the regular expression to filter out the data!
and here you go!
System.IO.StreamReader rdr = new System.IO.StreamReader(filename);
string allText = rdr.ReadToEnd();
