What is CSV File Format?
A CSV is a comma-separated values file, which allows data to be saved in a tabular format. CSVs look like a garden-variety spreadsheet but with a . csv extension. CSV files can be used with most any spreadsheet program, such as Microsoft Excel or Google Spreadsheets.
Key Features:
- Simplicity: CSV files are easy for both humans to read and computers to process.
- Compatibility: One of the best things about CSV is that it works well with a lot of different apps and platforms.
- Flexibility: It can handle various data types and sizes without needing a complex structure.
You can work with and analyze data in CSV files. This is especially true when you must transfer or share a lot of information between systems.
More Information
The CSV data exchange format is extensively supported by personal, business, and scientific software. It's particularly valuable for transferring data between applications because of its simplicity and broad compatibility. CSV files are commonly used to export data from databases or spreadsheets, enabling easy data import into other software.
Common Uses:
- Exporting data from a financial application to a customer relationship management (CRM) system.
- Migrating survey results from survey tools to data analysis platforms.
- Transferring contacts from email services to address organizers or other email platforms.

CSV files are often used as an intermediary format to move data from proprietary formats (e.g., .XLSX, .ACCDB) into other applications that do not support those specific formats, thus enabling data interoperability.
Forensic Insights on CSV Files
Because CSV files are simple and easy to retrieve, they are important in the field of digital forensics. CSV files can be examined by analysts to ensure data validity, integrity, and to look for any changes made throughout the data exchange process. In a forensic investigation, CSV files are easy to analyze and validate because they are plain text files.
