File conversion system and file conversion method

The invention relates to a file conversion system and a file conversion method. The file conversion method comprises the following steps: automatically obtaining file conversion data containing a testmode to be converted; carrying out file conversion so as to convert the test mode to be converted into a format of a target test mode; renaming the target test mode after the file conversion; compiling the target test mode; and storing the renamed target test mode. The file change system comprises a file conversion server and at least one test machine for testing a wafer, wherein the file conversion server is used for automatically obtaining the file conversion data containing the test mode to be converted, converting the test mode to into the target test mode, renaming the target test mode,compiling the target test mode and storing the renamed target test mode. The invention ensures that file conversion steps can be simplified, unified and automatically operated completely. A test module after the file conversion can be repeatedly used so as to reduce man-made careless mistakes and staff for extra hour work, improve the working efficiency, reduce mass-production preparation time, have high system extendibility and reduce the relevant cost.
