The invention provides a method for realizing file data automatic uploading synchronization based on kettle. The method comprises the following steps that step S1, the detail data of certain file is extracted on the basis of a kettle tool; SMTP service is configured so that the detail data is output in an Excel form at regular time; step S2, the file data is automatically uploaded to a target system in an incremental form, so that the automatic updating of the data is realized. On the basis of the existing service resources, the technological means such as the kettle and the database are combined for realizing the timed automatic synchronization and uploading on basic data files; the data updating timeliness is ensured; the productivity is liberated; the current situation of manual operation is changed; the work efficiency is improved.
