Extract text from OCA files
To convert your OCA file to another format, you need Microsoft Visual Basic or other Developer software.
To convert other file formats to the "Cache File" file type, you need software like Microsoft Visual Basic or a similar tool.
The .OCA file extension represents a collision between legacy development archives and modern configuration standards. Most commonly (62%), it is a Custom Control Library Type File (ActiveX Cache) generated by Microsoft Visual Basic. These binary files act as a cache for OCX controls, storing type library information to speed up the development environment. They are proprietary, tied to specific versions of the Windows registry, and cannot be "converted" in the traditional sense; they are usually regenerated automatically if deleted.
However, in enterprise infrastructure, an .OCA file is often an HPE One Config Advanced export. These are actually formatted as XML but lack the standard extension, meaning browsers and text editors won't open them by default. Users struggle to view these configurations without manually renaming the file or using specific HPE tools. Less frequently, .OCA refers to open geometry data compatible with FreeCAD.
For the HPE variant, the best conversion workflow is to XML (for editing) or PDF (for documentation/archiving). For the CAD variant, converting to STEP or STL ensures compatibility with modern 3D printers and modeling software like Blender.
Convert.Guru analyzes your OCA file, detects the exact format, and lets you read the text inside.
Users also converted PDF, O, LIB and BAS files.
If you want to convert OCA file to JS, TS, PY, JAVA, CPP, C, CS, PHP, RB, GO, RS or SWIFT, you can use Microsoft Visual Basic or similar software from the "ActiveX Control Cache" category. In the File menu, look for Save As… or Export….
To convert SH, PY, KT, PS1, SWIFT, LUA, PL, JAVA, SCALA, JS, VBS or TS files to OCA, try Microsoft Visual Basic or another comparable tool in the "ActiveX Control Cache" 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 OCA converter.
