Data formats are ways to formally represent different kinds of data following commonly agreed structure and semantics. Data formats are usually machine-readable, meaning that they can be created and processed by computer programs. Examples of common data formats are portable document format (suffix .pdf) for text and image documents, hypertext markup language (suffix .html or .htm) for web content, and plain text (suffix .txt).
