Convert UI4JD to TXT

Can you convert UI4JD to TXT?
QUICK ANSWER
Is it possible to convert UI4JD to TXT?
No - not a direct conversion.

A .ui4jd file holds JSON in plain text, so you don't convert it to .txt - you just open it in any text editor to read or copy the content. If you truly need the .txt extension, save a copy with a new name, though nothing about the data changes.

Why convert UI4JD to TXT?

The .ui4jd extension is only a label the Project 4JD UI add-on uses; the bytes inside are ordinary UTF-8 JSON, the same kind of text a .txt file stores. There is no separate binary layer to decode, so a format conversion serves no purpose.

How to convert UI4JD to TXT

Visual Studio Code FREE

Open the .ui4jd in VS Code to read the JSON with syntax highlighting; if you want a .txt, use File > Save As and type a name ending in .txt.

TextEdit (macOS) FREE

Open the file in TextEdit in plain-text mode, then File > Duplicate and save as .txt; the JSON content is identical.

About these formats

Quality & what to watch

  • Changing the extension to .txt does not reformat or simplify the JSON - you still see the same braces, keys and values.
  • If you rename rather than 'Save As', the add-on can no longer find the file, so keep the original if the pack still needs it.
  • Windows may hide the real extension, so confirm you actually created .txt and not file.ui4jd.txt.

Frequently asked questions

Why is there no real ui4jd-to-txt converter?
Because .ui4jd is already plain-text JSON; a converter would just copy the same characters.
Will I lose data saving it as .txt?
No, the text is byte-for-byte the same; only the file extension differs.
Can Minecraft still use the file if I rename it to .txt?
No, the add-on looks for the .ui4jd name, so keep or copy the original.
Do I need special software to read it?
No, any text editor opens it; VS Code just adds helpful JSON highlighting.
