What is an SDA file?
The .SDA file extension is used for several different file formats. Most frequently, it is a Microplate reader data file created by Molecular Devices SoftMax Pro. Another common use is for CAD data files and steel reinforcement schedules used in Nemetschek Allplan. Business systems also use this extension; SAP NetWeaver uses .SDA for Software Deployment Archives, which are standard .ZIP compressed packages.
You might also encounter .SDA files as electronic journals from Sharp cash registers, or as StarDict dictionary files. Historically, the .SDA extension is well known as a StarOffice Drawing file, a vector graphics format developed by the Apache Software Foundation.
How to open SDA files?
Because the .SDA extension has multiple possible meanings, you must identify the actual format of your file before opening it. If it is an SAP Software Deployment Archive, you can rename the file extension to .ZIP and extract it using archive tools like 7-Zip.
If the file is an old StarOffice Drawing, open source office suites like LibreOffice Draw or Apache OpenOffice can open it. Specialized scientific data and engineering files require their original software, such as SoftMax Pro or Allplan.
Software and tools
Guessing the correct software can be difficult. viewer.online/sda analyzes .SDA files to identify their exact format and creator software, shows which programs can open the file, and usually previews it.
Once identified, you may want to share the data. We recommend file conversion to sensible target formats on convert.guru. Depending on the original file, you can convert graphics to .PDF or .PNG, and data tables to .CSV.
Summary
viewer.online/sda directly opens and previews .SDA files in the browser, eliminating the need to install software or troubleshoot compatibility issues.
