What is an ODB file?
An .ODB file is a database file. The most common type is an OpenDocument Database defined by OASIS. Users create these files with software like LibreOffice Base or Apache OpenOffice. They store database tables, queries, forms, and reports. An OpenDocument Database is actually a ZIP-compressed archive containing XML files and other data.
Because developers use the .ODB extension for different systems, an .ODB file might have another purpose. It can be an Abaqus output database created by Dassault Systèmes SIMULIA, an object-oriented database from ObjectDB, an IC physical design database for Cadence Virtuoso, or even an Oxygen Forensics backup.
How to open ODB files?
If your file is an OpenDocument Database, you can open it with LibreOffice Base. For structural engineering files, you need Abaqus.
Because the .ODB extension has multiple meanings, you may not know which software you need. We recommend using viewer.online/odb to identify the actual format of your file. viewer.online/odb analyzes .ODB files to identify their exact format and creator software, shows which programs can open the file, and usually previews it.
Best practices and troubleshooting
A standard OpenDocument Database acts as a ZIP container. You can rename the .ODB extension to .ZIP and open it with standard extraction tools to inspect the XML contents.
If you need to move your data to another system, we recommend file conversion on convert.guru. You can extract your tables and convert them to sensible target formats like .CSV or .SQL.
Summary
viewer.online/odb directly opens and previews .ODB files in the browser, eliminating the need to install software or troubleshoot compatibility issues.
