A comma-separated values (CSV) file is a simple file format used to store tabular data, such as a spreadsheet or database.
In concrete, CSV is a text file that uses a comma to separate values. Each line of the file is a data record. Each record consists of one or more fields, separated by commas.
A CSV file will open as a .csv file in your computer's native text editor, but it's recommended that you use a spreadsheet program to view and edit your CSV files instead. To work a CSV file we recommend either:
Google Sheets (if you don't mind sharing your data with Google)
a software, like Libre Office
Using the CSV file with Google Sheets
Opening the CSV
On the Google Sheets page, click Blank in the Start a new spreadsheet section.
From the Untitled Spreadsheet page, go to File > Import...:
Locate and select the CSV file that you want to edit.
In the Import file dialog, select your preferred options under the Import action: 'Separator character: comma', and 'Convert text to numbers, dates, and formulas: No'.
On top, when the file is ready, click 'Open now'
Export the CSV
When you are done viewing or editing your CSV file in Google Sheets, you can export it as a .csv file to your computer.
From your CSV spreadsheet page, go to File > Download as > Comma-separated values (.csv, current sheet).
Using the CSV file with Libre Office
Opening the CSV
As you open a CSV file with Libre Office, you must pay attention to respect the following criteria:
Character Set: Unicode UTF-8
Column type: Text
Your CSV files must always use UTF-8 encoding
If you are updating a CSV file export, then remember to confirm the UTF-8 encoding to avoid generating unwanted special characters in your file. If you save your file after forgetting to confirm its UTF-8 encoding, then your data will be corrupted when you upload it as a new spreadsheet. Magnetiq can't recover corrupted files for you.
