What Is PM Dumper 3 and Why Should You Care?
If you’ve ever dug deep into Minecraft modding, you know how valuable raw game data can be. Whether you’re balancing a custom modpack, debugging recipe conflicts, or simply satisfying your curiosity about how many types of stone exist, having a way to extract that information quickly is a game-changer. PM Dumper 3 was built exactly for that purpose—it’s a Minecraft Forge mod that lets you dump all sorts of game registries into neat CSV files. Think of it as a data miner for your own single-player world or server, giving you spreadsheets filled with blocks, items, entities, and much more.
Important: This Mod Is Outdated
Before you rush to install it, you should know that PM Dumper 3 is no longer maintained. The developer has moved on to a newer project called CraftDumper, which carries the torch forward with better support and more features. However, PM Dumper 3 still works perfectly fine on older versions of Minecraft (specifically 1.12.2, where Forge modding was at its peak), and many players continue to rely on it for their legacy worlds. If you’re playing on a more recent version, definitely check out CraftDumper instead. For everyone else sticking with the classics, PM Dumper 3 remains a reliable tool.
Getting Started: The One Requirement
PM Dumper 3 doesn’t ask for much, but it does need Shadowfacts' Forgelin to function. Forgelin is a small library mod that provides Kotlin language support for Forge, and without it the dumper will simply crash. Installing it is straightforward—drop both JAR files into your mods folder, and you’re good to go. If you’re looking for a hassle-free way to get started, you can grab PM Dumper 3 directly through the foxygame.net launcher, which offers a modern interface and a built-in mod downloader that streamlines the whole process. This launcher handles dependencies like Forgelin automatically, so you won’t have to hunt down extra files manually.
What Can You Dump? The Full List
The mod supports a surprisingly wide range of data categories. Every time you run a dump, it reads the game’s internal registries and writes them to files inside the .minecraft/pmdumper folder. Here’s what you can extract:
- Advancements
- Biomes
- Blocks
- Capabilities
- Enchantments
- Entities
- Fluids
- Food (saturation and hunger values)
- ItemStacks (all items with metadata)
- Loot Tables
- Models
- Potions
- Shaped Recipes
- Shapeless Recipes
- Smelting Recipes
- Sounds
- Tile Entities
- Villager Professions
That’s eighteen different dumpers, each covering a core part of the game. For modpack developers, this is pure gold—you can instantly see which items are registered, how recipes overlap, or which biomes generate in your world.
Using the Command: A Simple Syntax
All the magic happens through a single in-game command. Open your chat and type:
/pmdumper <all|dumper name> <csv|amounts|csv_amounts>
The first argument picks the dumper. You can use all to run every dumper at once, or specify a name like blocks, entities, or food. If you’re not sure what’s available, just type /pmdumper without any arguments, and it will list all supported dumpers right in chat.
The second argument controls the output format:
- csv – Generates a standard CSV table with all the dump data. Each row represents one entry, and columns vary by dumper type.
- amounts – Creates a CSV file that counts how many of each entry exist. Useful for quick statistics.
- csv_amounts – Combines both formats into a single file, giving you the full data plus the counts.
After executing the command, you’ll find the resulting files in the .minecraft/pmdumper directory. No need to restart the game—the files are written instantly.
Practical Examples
Let’s say you want to see every item registered in your modded instance, including metadata variants. You’d type:
/pmdumper items csv
A file named something like ItemStack.csv will appear, containing columns for item ID, display name, max stack size, and more. If you’re only curious about how many different food items exist, you could run:
/pmdumper food amounts
This gives you a compact count without overwhelming you with details. The csv_amounts exporter is perfect when you need both the raw list and a summary—for example, dumping all blocks with their counts to check for ID conflicts in a large modpack.
The images below show what a typical ItemStack dump looks like, along with the amounts view. (Note: the original mod page included screenshots of these outputs, but you can easily generate your own with the command above.)
Why PM Dumper 3 Still Matters
Even though it’s outdated, PM Dumper 3 fills a niche that many modern tools overlook. It’s lightweight, does exactly what it promises, and doesn’t require any complex configuration. For players stuck on 1.12.2 due to beloved mods that never updated, this dumper remains a staple in the toolkit. It also serves as a learning resource—new modders can study the CSV outputs to understand how Minecraft structures its registries, which is invaluable when creating custom content.
If you’re planning to move forward, the CraftDumper project takes the same concept and extends it to newer versions with additional dumpers and better performance. But if you’re knee-deep in a 1.12.2 modpack and need to audit your recipes or generate a block list for documentation, PM Dumper 3 will get the job done without fuss.
Staying Connected
The mod’s community still shares tips and custom dumpers on Discord and GitHub, though you’ll need to search for those channels manually since links aren’t provided here. The original author’s repositories often contain useful forks and discussions that can help you troubleshoot any issues.
Conclusion
PM Dumper 3 is a straightforward, no-nonsense data extraction tool for Minecraft Forge. With support for eighteen different data types, flexible export formats, and a dead-simple command interface, it turns the game’s hidden registries into readable spreadsheets. While it’s been superseded by CraftDumper for modern versions, it remains a reliable companion for legacy 1.12.2 setups. Whether you’re a modpack creator, a server admin, or just a curious player, having a quick way to dump game info can save hours of manual digging. So if you’re still running those older worlds, give PM Dumper 3 a try—you might be surprised how much you learn about your own modded environment.
