Editing an RBXL file

I feel like this is the most fitting place to ask this
Is there any way to edit an RBXL file directly? Attempting to open it with a texteditor yields a half-readable piece of text that contains some unknown characters (or perhaps this is an apple issue? Most of the weird characters seem to be apple specific characters like the apple symbol)

And assuming I want to replace all of a specific number inside the actual game (such as a gamepass or badge id), would I be safe to assume that simply replacing all of its appearences inside the RBXL file would work and wouldn’t cause any issues?

Probably would cause issues. You’re hacking at that point. Replacing a number may or may not work.
What you’re seeing is a serialized Roblox .rbxl or .rbxmx file (typically for places or models). These files contain metadata, objects, and properties saved in a structured but non-human-readable format, often in binary or a hybrid text-binary encoding. You would also need a hex editor not a text editor.

Was tryna do it via code, and code cant really open roblox studios

Ah so thats why

I believe I’ve seen other people talk about doing this, so I thought it might be possible
Anyways ill check it with a hex editor ig, maybe thatll be more readable

No it will not be more readable … but it will save the file the correct way, as hex.

Guh

In that case, is there really no way to get what would be displayed in Roblox studios atleast in terms of certain values?
(Like properties and scripts)

Probably not, and hacking a hex file is totally hit-and-miss. No real way to actually program like that. Maybe someone made a reader, but why bother? Roblox Studio is made to edit that file.

The goal was to clone my own game with gamepasses, and to automate replacing gamepasses in the place would require me to do so with the RBXL file :sob:

Numbers are one of the few things you can mess with a bit. If they are all there in readable format. If you understand hex you can do a bit more. Still don’t see the need for this. You can do all this in the studio with ease.

MaximumADHD made a C# library to edit/view Roblox Binary files. I don’t know about other languages.
