You can use the Export MaxCompute Table to OSS component to export MaxCompute tables to Object Storage Service (OSS). Each row of data in a MaxCompute table is exported as a valid JSON object in an OSS data file. The OSS data file is in the JSON Lines format. The file as a whole is not a valid JSON object. You can click here to view an example. A file that contains a large amount of data may be split into multiple files.
