Extract text from Zope export files (ZEXP)
To convert ZEXP export files to another format, you need Plone or other Database software.
To convert other file formats to the "Zope Database Export" file type, you need software like Plone or a similar tool.
The .zexp file is a serialized export of objects from a Zope Object Database (ZODB), primarily utilized by the Plone Content Management System. These files serve as targeted backups or transfer mechanisms for moving site content, user directories, and specific configurations between different server instances. They contain Python "pickled" data that represents a hierarchical graph of objects rather than traditional relational data.
The major disadvantage of the .zexp format is its extreme vendor lock-in. It is a proprietary, closed structure that explicitly requires a running Zope application server with the exact same Python modules installed to be successfully imported. If a Python class definition is missing or outdated on the target server, the import will fail with a "Broken Object" error. Furthermore, you cannot open a .zexp file in standard relational database tools like DBeaver or basic text editors.
Standard online converters inevitably fail to process .zexp files because they lack the specific Zope/Python environment required to unpickle the object graph. To migrate data completely out of Zope, the best target formats are JSON, XML, or CSV, but this generally requires executing a custom Python export script inside the original server environment rather than converting the .zexp file itself.
Because this file format is difficult to open or convert, often only the original software can properly read or export the data. However, just drag and drop your file to see what it is and convert it if supported. convert.guru can identify the file format, inspect the binary file, and reveal embedded text strings or raw content. If our analysis detects readable metadata or text nodes within the serialized stream, partial data extraction and viewing may still be possible.
Convert.Guru analyzes your ZEXP file, detects the exact format, and lets you read the text inside.
Users also converted ZPT, BASE and IMX files.
If you want to convert ZEXP file to , you can use Plone or similar software from the "ZODB Object Export Storage" category. In the File menu, look for Save As… or Export….
To convert files to ZEXP, try Plone or another comparable tool in the "ZODB Object Export Storage" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our ZEXP converter.
