You’ll know you’re dealing with CSV files if the .csv file extension is something like myData.csv (also depends if your operating system is set up to see what type of file it is) or if you open the file. in a text editor and notice that the dates are separated by commas.

Even if you open the CSV file in Excel and apply some formatting, such as adjusting the column widths to see the data, Excel will still warn you that it can’t save the formats you’ve added. You will get a warning like this:

CSV files are used as a way to communicate data between different applications. Let’s say you have a database application and you want to export data to a file. If you want to export it to an Excel file, then the database application should support exporting to XLS* files.

However, because the CSV file format is extremely simple and lightweight (much more so than XLS* files), it is more easily supported by various applications. In basic usage, you have a line of text, with each column of data separated by a comma. And it was done. And this simplicity makes it easy for developers to create export/import functions with CSV files to transfer data between applications instead of more complex file formats.

Although the format is simple, it’s still not an Internet standard, although there is a draft for it (it’s the shortest RFC I’ve seen, by the way, which is pretty nice). There are some problems to overcome with CSV files, and some applications handle it in different ways.

For example, what if your data contains a comma? How to separate it? What about line breaks (like Alt+Enter)?

Let’s talk about how to overcome the following two problems with CSV files: commas in the data and newline handling.

As you can see, even though we only want data in columns A and B, some data has gone into column C. This is because of the commas that exist in the data. So how do you get around it?

Let’s say you have a new row of data in an Excel file that looks something like this:

It might be hard to tell, but basically this example uses the quotes again, but this time it allows the newline character to be in the data and span two lines.

At this point, you may be wondering, “What happens if there are quotes in my data?” That’s a good question, and the answer might be familiar to you if you’ve ever had to put quotes in the output of a formula.

How To Create A Csv File: 2 Simple Methods

If your data is not already surrounded by quotes, you can just add a quote. However, if you use quotation marks to delimit data because it contains a comma, you must “escape” the quotation marks by adding another quotation mark.

The first row of data. The second column contains a “quotation mark” in the data, and Excel takes it literally when processing the file. So you’ll see that the menu actually goes to the cell in B2.

Here in the second column, you’ll see that the comma inside the quotation marks actually splits the data into the third column. This is because the entire data string was not enclosed in quotation marks, so Excel interpreted it as two different columns of data, rather than one.

Here we show how to correctly do what we were trying to do in the second row of data. We wrapped the second column in quotes and left the desired quotes in our data by adding another quote. Excel interpreted it the way we wanted by having only two columns of data and quotes in the data.

How To Create Csv File

This last example shows how to add a quote to another column that also contains a comma. So we need to add comma quotes so that Excel doesn’t split the data, and we also need to add quotes so that Excel doesn’t think the data is finished before the word “quote”.

CSV files do not always need to use a comma to separate values ​​in the data. Many applications allow you to use a set of commonly used delimiters, or you can enter your own. However, you cannot have multiple delimiters in a single CSV file. Once you select a delimiter, it is a file-wide delimiter.

Although there are applications that allow you to specify a different character separator, Excel has no native way to change the separator. However, you can change the default list separator in your operating system, which would work, but I guess we’ll have to save that for another post.

For me, I prefer to use the pipe | character. It’s easy to see and almost never used in data (unless you’re saving PowerShell snippets), making it a unique choice for saving to CSV.

How To Create Csv File

If you intend to use a character other than a comma to separate values, there is an important line that you must ensure is at the beginning of the file. For example, let’s say we have this data:

The marker is obviously a pipe | character. But if you open it in Excel it will look like this:

Notice how all the data is in column A? This is because Excel does not find the comma to separate values, which is its default separator. To tell Excel to use a different delimiter, you need to add a special line at the beginning of the file:
