Convert OTPU to OGGU

QUICK ANSWER
Is it possible to convert OTPU to OGGU?
Yes - OTPU converts to OGGU.

An .otpu file is a graph template (axes, styles, plot types) with no data. In Origin you plot a dataset using the template to build a real graph, then use File: Save Window As and choose the Origin Graph (*.oggu) type. The template on its own can never be an .oggu graph.

Why convert OTPU to OGGU?

A template defines how a graph looks, but people often want to hand off one finished, standalone graph window. An .oggu file stores a single graph you can reopen or drag into another project, which a template does not provide.

How to convert OTPU to OGGU

OriginLab Origin (plot then Save Window As) PAID

Select your data and plot it through the .otpu template (via the Template Library or Plot menu), then choose File: Save Window As and pick *.oggu.

OriginPro PAID

Same in OriginPro: apply the graph template to data, then use File: Save Window As to export the graph window as .oggu.

Quality & what to watch

  • The template has no data, so the .oggu only reflects whatever dataset you plot into it.
  • An .oggu is a single graph window, not a full project, so linked workbooks are not embedded the same way.
  • Both are Origin 2018+ Unicode formats and open only in Origin or OriginPro.

Frequently asked questions

Can I turn an .otpu into an .oggu without data?
No. You must plot a dataset using the template first, because an .oggu stores an actual graph, not a blank style.
What is the difference between the two?
.otpu is a reusable graph template; .oggu is one specific graph window created from data.
Which menu saves the graph as .oggu?
With the graph active, use File: Save Window As and select the *.oggu file type.
Do I need a special program?
Yes, OriginLab Origin or OriginPro 2018 or later handles both formats; nothing else does.
