2.89 FAQ-927 Is there some way to convert the new OPJU file format into the older OPJ format?

Last Update: 4/12/2018

Origin 2018 introduced a new Unicode-compliant (UTF-8) project file type -- the OPJU file. These files cannot be opened in earlier versions of Origin (though, it should be noted that Origin 2018 and newer versions retain the ability to save files in the older OPJ format).

If you cannot open an OPJU file with your Origin software, do this:

  1. Download the Origin Viewer by visiting this page on the OriginLab website.
  2. Unzip the contents of the Viewer file download.
  3. Double-click on the EXE to run the Viewer (no installation required), then choose File: Save Project As from the Viewer menu and re-save the project as an OPJ file.


For more information on the Origin Viewer, visit this page on the OriginLab website.
