A TAB file is a data file created by Typinator, a typing shortcut program for macOS. It contains a set of typing abbreviations and their associated words added by users. TAB files are referenced by Typinator to insert associated words when abbreviations are typed in documents, web browsers, and other programs on a computer.

Typinator is a program used to increase users' typing efficiency. It allows users to type shortcuts instead of whole sentences, which is especially helpful when repeatedly typing the same sentence or phrase. Typinator also serves as an AutoCorrection tool for misspellings. NOTE: TAB files are similar to the more common .TYSET file.
