What is it?
CSV (Comma-Separated Values) is a plain text format that stores tabular data as rows of values separated by commas, making it the most universal format for exchanging spreadsheet and database data between applications.
Understanding CSV helps you choose the right format for your specific needs and workflow.
Technical Specifications
Pros & Cons
Advantages
Every spreadsheet app, database, and programming language can read and write CSV without special libraries.
CSV is plain text - you can open and edit it in any text editor and immediately understand the data.
No formatting, no metadata - CSV files are extremely compact compared to XLSX or database exports.
Any application or script can produce valid CSV with a simple loop, making it ideal for data exports.
Disadvantages
Everything is stored as text - dates, numbers, and booleans must be interpreted by the receiving application.
CSV stores only raw data - no bold text, colors, merged cells, or any visual formatting.
Special characters and non-ASCII text often cause problems when files are opened in different locales.
CSV cannot represent relational data or multiple tables - you need multiple files or a different format.
When to Use It
Here are the most common scenarios where CSV is the right choice:
Datenbankexporte
Exporting database tables to CSV for backup, analysis, or migration to another system.
Datenanalyse
Input format for Python pandas, R, Excel, and virtually every data analysis tool.
CRM- und Marketingdaten
Contact lists, email subscriber exports, and sales data shared between marketing tools.
Anwendungsintegration
Moving data between applications that do not share a native integration or API.
How to open a CSV file
