Convert JFPROJ to JSON

Can you convert JFPROJ to JSON?

QUICK ANSWER
Is it possible to convert JFPROJ to JSON?
No - not a direct conversion.

A .jfproj is Microsoft Font Maker's project file, and its data is already stored in JSON. Renaming it to .json just lets a text editor open it, but no other program understands the structure. There is no standard tool that turns a font project into meaningful, reusable JSON, so the real goal is almost always exporting the finished font instead.

Why convert JFPROJ to JSON?

.jfproj stores glyph outlines, spacing and sample text as JSON, so people assume it converts cleanly to .json. In practice the content is a proprietary Font Maker schema that only Font Maker reads - there's no application or benefit to producing a standalone JSON file from it.

How to convert JFPROJ to JSON

Rename to inspect the JSON FREE

Copy the file and rename it to .json, then open it in VS Code or Notepad to read the raw project data. This is for viewing only, not for use in another app.

Export a real font with Microsoft Font Maker FREE

Open the .jfproj in Microsoft Font Maker and use Export to produce a .ttf, which is the usable output most people actually want.

Quality & what to watch

  • The file already contains JSON, so a rename doesn't convert anything - it only changes how your OS labels it.
  • No third-party software can import Font Maker's JSON schema, so the extracted JSON has no practical use elsewhere.
  • If your goal is a font you can install or use on the web, export to .ttf and convert onward instead.

Frequently asked questions

Isn't .jfproj already JSON?
Yes. Font Maker stores the project as JSON internally, which is why renaming to .json shows readable text - but the layout is specific to Font Maker.
Can another program read the JSON from a .jfproj?
No mainstream font editor imports Font Maker's schema. The JSON is only meaningful to Microsoft Font Maker itself.
What should I convert a .jfproj to instead?
Export it to .ttf in Font Maker. From TTF you can reach OTF, WOFF or WOFF2 with a font converter if needed.
