What is CSV encoding?

In simple words, it is a method of translating the characters (numbers, letters, punctuation, etc.) that are in your data into a computer language represented by a binary code consisting of numeric values and vice versa.

These are all special characters

Let’s imagine that you have created a CSV file full of data with different alphabets and special characters. When you saved your file, the system actually saved it in binary code. You sent the file to a friend of yours by e-mail. Now his computer, in order to open your file and show all the characters, needs a key, which is the character encoding.

What encoding is best to use for data?

With all the variety of encodings for the average user, it is always recommended to use UTF-8 encoding. It contains 1,112,064 characters, which includes almost any character you can type in any language. This means that you can type any text, numbers, punctuation, emoji — anything — and, using the UTF-8 encoding, the computer will get the key it needs to open the file without errors.

If you use a different encoding key, you may encounter error messages or just a file that looks like this when opened:

Question marks instead of data are errors due to the encoding choice, i.e. there are no such characters in the key and therefore the system outputs question marks.

Most modern programs use UTF-8 encoding when saving files. For example, Google Sheets uses UTF-8 by default. However, if you are using Excel, you may need to check that you are using UTF-8 encoding. You can usually do this when you save your data in CSV.

You can do this by*:

  1. When saving file select «Save As» and select «.CSV»
  2. Name your file
  3. At the bottom of this dialog box, select «Tools» and then «Web options»
  4. Head to the «Encoding» tab and in the «Save this document as:» dropdown, choose Unicode (UTF-8).
  5. Now you save your file.

The easiest tip to avoid errors is to always use UTF-8 encoding, then most likely your CSV file can be opened and read by most modern programs and spreadsheets.

What is a CSV File and How to Open the CSV File Format

What is a .csv file? CSV stands for Comma Separated Values. A CSV file is a plain text file that stores tables and spreadsheet information. The contents are often a table of text, numbers, or dates. CSV files can be easily imported and exported using programs that store data in tables.

CSV File Format

Usually the first line in a CSV file contains the table column labels. Each of the subsequent lines represent a row of the table. Commas separate each cell in the row, which is where the name comes from.

Here is an example of a CSV file. The example has three columns, labeled ‘name’, ‘id’, and ‘food’. It has five rows including the header row.

name, id, favorite food quincy, 1, hot dogs beau, 2, cereal abbey, 3, pizza mrugesh, 4, ice cream

Here is how that file looks in a spreadsheet.

Since a CSV file is just a text file, you can create one in almost any text editor. You can also export CSV files from almost any spreadsheet program, such as Microsoft Word, OpenOffice Calc, or Google Sheets.

How to open a CSV file

Opening a CSV file is simpler than you may think. In almost any text editor or spreadsheet program, just choose File > Open and select the CSV file.

For most people, it is best to use a spreadsheet program. Spreadsheet programs display the data in a way that is easier to read and work with than a text editor. We’ll go into more detail on opening a CSV file in Microsoft Excel, OpenOffice Calc, and Google Sheets.

Open a CSV file Microsoft Excel

If you already have Microsoft Excel installed, just double-click a CSV file to open it in Excel. After double-clicking the file, you may see a prompt asking which program you want to open it with. Select Microsoft Excel.

If you are already in Microsoft Excel, you can choose File > Open and select the CSV file. If you don’t see the file you want to open, you may need to change the file type to be opened to «Text Files (*.prn, *.txt, *.csv)». Excel will display the data in a new workbook.

You can also import data from a CSV file into an existing worksheet.

In the preview dialog box, you have a few options:

  • Select Load if you want to load the data directly to a new worksheet.
  • Select Load to if you want to load the data to a table or existing worksheet.
  • Select Transform Data if you want to load the data to Power Query, and edit it before bringing it to Excel.

Open a CSV file OpenOffice Calc

If you already have OpenOffice Calc installed, just double-click a CSV file to open it. After double-clicking the file, you may see a prompt asking which program you want to open it with. Select OpenOffice Calc.

If you are already in OpenOffice Calc, you can choose File > Open and select the CSV file.

Open a CSV file Google Sheets

First, open a new spreadsheet file in Google Sheets. The fastest way is to go to https://sheets.new.

Next, select File > Import.
