Export format

This page contains the format used by EXPORT DATABASE and IMPORT DATABASE tools. The file is a zipped JSON.

NOTE: Even if the file is 100% JSON, there are some constraints in the JSON format, where the field order must be kept. If you prettify the file, the import couldn't work anymore.
