What is a standard file format for transferring lists such as addresses and contacts?

The standard file format commonly used for transferring lists such as addresses and contacts is Comma Separated Value (CSV). CSV files are straightforward text files that use commas to separate values, making them easy to create, read, and process across various applications and platforms.

This format is particularly well-suited for data that is structured in rows and columns, which is typically how address and contact lists are organized. Because many software applications, including spreadsheet programs and database systems, can easily import and export CSV files, they have become a universal standard for data interchange.

Other options, while useful in specific contexts, do not match the versatility and widespread acceptance of CSV for transferring lists. For example, PDF files are primarily used for fixed-format documents and not ideal for data manipulation. vCard is specifically designed for electronic business cards, catering to contact details but lacking the general applicability of CSV for various types of lists. Excel spreadsheets, while powerful for local data manipulation, are not as commonly used for simple data transfer in a format that can be easily imported into a variety of tools without specific spreadsheet software.
