About MSPROJ files
The .msproj file is a proprietary Message Studio Project created by Nintendo. It is used internally by game developers to manage in-game text, dialogue, and localization data across multiple languages for Nintendo consoles. Opening this file natively requires Nintendo's official Message Studio software, which is strictly locked behind a Non-Disclosure Agreement (NDA) and only available to licensed developers.
Users typically need to convert this file when datamining, modding games, or attempting to translate in-game dialogue without the official development kit. A major disadvantage of the .msproj format is its highly proprietary nature. The files often contain complex, undocumented data structures and proprietary formatting tags. Standard online converters fail to process these files because they lack the specific parsing logic required to read Nintendo's internal SDK formats.
The best conversion targets for extracting this data are standard structural text formats like XML, JSON, or CSV. Converting to these formats makes the dialogue readable in any text editor or spreadsheet software, though some specific in-game formatting codes (like text color or delays) may be lost in the process.
Because this file format is difficult to open or convert, standard tools will usually output errors.
Convert.Guru analyzes your MSPROJ file, detects the exact format, and lets you read the text inside.
