This example shows how to perform aggregate computations such as Sum, Average, Min, and Max on the columns of a. The example principles that are shown here can be applied to other types of structured text. Copy the following lines into a file that is named scores. Assume that the first column represents a student ID, and subsequent columns represent scores from four exams.

The query works by using the Split method to convert each line of text into an array. Comma separated values text files. In a comma-separated values CSV file the data items are separated using commas as a delimiter , while in a tab-separated values TSV file, the data items are separated using tabs as a delimiter. Column headers are sometimes included as the first line, and each subsequent line is a row of data. Read and Write CSV file in vb. CSV file in VB. NET, Write into. CSV file in vb.

Net, Writing data to. In our example we are writing the Customer information using the StreamWriter with separates each field of text by comma ,. Read that file using the OleDbConnection. At the moment, we've only told VBA to open the file. We haven't actually done anything with it. The way you normally do something with a file is to loop round, grabbing each line as you go.

We'll use a Do Until loop for this:. Notice the strange end condition: EOF 1. The first three items before the comma refer to a single line of input from your file number 1. After the comma, you tell VBA where you want to place this line. This will be a variable. We've called ours LineFromFile. Every time round the loop, a new line will be grabbed from the text file and placed in this variable. Now that you have a line from your text file, you need to do something with it. However, the line will still have all the commas in it.

So the first line for us will be this:. You need to parse the lines from your text file in some way. A good way to parse a line is with the Split function you met earlier. By using Split, you can place each item from a line into an array:.

Between the round brackets of Split , we have the variable we want to split, which is LineFromFile. After a comma, we have the separator we want to look for.

The separator is the comma, for us. When Split has finished, we'll have an array called LineItems. Our text file always has three items per line first name, last name, ISBN.

So we know the array goes from 0 to 2 positions. We can now go ahead and place each item into a cell on the spreadsheet:. Between the round brackets of Offset we have the row number and the column number. We set this to 0 earlier. We'll increment this variable shortly. The columns are always offset at 0, 1 and 2.
