What is the CSV file?
A CSV file is a comma-separated values file, which means that it is a text file that contains data that is separated by commas. CSV files are often used to store data from databases or spreadsheets, and they can be opened in spreadsheet programs like Microsoft Excel or Google Sheets.
CSV files are very simple to work with and are supported by nearly all spreadsheet and database applications. They are typically saved with a .csv file extension. Most CSV files use commas to separate the values, but other delimiters, such as tabs or spaces, can be used instead.
How to make?
There are many ways to create a CSV file. In this article, we’ll focus on two common methods: using a text editor such as Microsoft Excel or Google Sheets, and using a dedicated CSV creation tool.
If you’re using a text editor:
- Open your text editor and create a new document.
- Type in the data you want to include in your CSV file, with each piece of information separated by a comma. For example:
John Smith,123 Main Street,555-1234
Jane Doe,456 Elm Street,555-5678
- Save your document as a CSV file. To do this in Excel, go to File > Save As, then select “CSV” from the drop-down menu next to “Save as type.” In Google Sheets, go to File > Download As, then select “Comma-separated values.”
If you’re using a CSV creation tool:
- Open your chosen CSV creation tool.
- Enter the data you want to include in your CSV file, with each piece of information separated by a comma.
- Save your document as a CSV file. Most CSV creation tools will have an option to do this; if not, simply choose “Save As” and select “CSV” from the drop-down menu next to “Save as type.”
That’s all there is to create a CSV file! Once you have your file saved, you can open it in any spreadsheet program to view and edit your data.
How to view a CSV file in a text editor?
When you open a file in a text editor, you will see the data values separated by commas. Each line in the file is a row of data, and each column is separated by a comma. For example, here is a small CSV file that contains three rows of data:
John Doe,32,New York
Jane Smith,27,Los Angeles
As you can see, each row of data is separated by a new line, and each column of data is separated by a comma.
How to Open in a Spreadsheet Program?
In order to open a CSV file in a spreadsheet program, such as Microsoft Excel, you will need to use the prog’s “Open” function. This can usually be found under the “File” menu. Once you have located the “Open” function, select it and then browse for the CSV file you wish to open. Once you have found the file, double-click on it to open it in the spreadsheet program.
