The invention is suitable for the technical field of data parsing and provides a file parsing method and a file parsing device. The parsing method comprises the steps of configuring file parsing strategies, which are correspondingly executed after a default special character is read, in different field parsing states in advance; reading data in a to-be-parsed file and obtaining the current field parsing state; finding out the file parsing strategy matched with the current field parsing state from the file parsing strategies, which are correspondingly executed after the default special character is read, in different field parsing states, configured in advance; and executing the corresponding file parsing process by using the file parsing strategy matched with the current field parsing state. A file can be quickly parsed, so that high efficiency of parsing is ensured, the method and the device have high fault tolerance, and nonstandard data can be processed.
