What is a CSV file?

CSV (Comma-Separated Values) is a simple text format for storing tabular data. Each line of the file represents a row in the table, and each value is separated by a comma or another delimiter such as a semicolon or tab.

CSV is a universal format supported by virtually all spreadsheet software, databases, and programming languages. It's popular for exporting and exchanging structured data between systems.

How to open CSV files

CSV files can be opened in virtually any spreadsheet or text editor, including Microsoft Excel, Google Sheets, and Notepad. They're widely supported for data import and export.

You can convert CSV files to XLSX, JSON, or XML using AnyConv or common data tools like Excel and Python scripts.

Did You Know?

CSV has no official standard - and that’s a problem

Despite its simplicity and popularity, CSV doesn’t follow a strict universal standard. This leads to quirks like different delimiters (comma, semicolon, tab) and inconsistent handling of line breaks or quotes - which can break files between systems.
