About WPN files
The .wpn file extension is primarily used as a Game Weapon Definition file for Starsector, an indie space combat roleplaying game created by Fractal Softworks. Under the hood, these files are written in standard JSON format. They store critical data for ship weapons, including damage types, sprite links, projectile speed, and energy costs. Because the extension is .wpn, standard operating systems do not know how to open it. Double-clicking will result in an error, frustrating players who want to create mods or rebalance weapons. Furthermore, standard online tools fail to process this niche extension, leaving users stuck. Converting .wpn to JSON or TXT is the best way to make the file readable in standard code editors like Visual Studio Code or Notepad++. This file format is often difficult to open or convert automatically because it is highly specific to the Starsector game engine. Often only the original software can properly read or export the data without causing crashes. However, just drag and drop your file onto convert.guru to identify the format, view it, and convert it when possible. Our platform can still identify the file format, inspect the file, and show text or internal content. If our analysis detects the supported underlying JSON embedded format, viewing or conversion to common text formats may still be possible.
Convert.Guru analyzes your WPN file, detects the exact format, and lets you read the text inside.
Users also converted INV_LOWRES, MIS and GUN files.
