OreDictDumper: Export Ore Dictionary to CSV/JSON
Minecraft modding is a world of hidden connections. Behind every crafting recipe, every ore unification, and every cross-mod compatibility lies the Ore Dictionary — an internal registry that tells the game which items from different mods are actually the same thing. A copper ingot from one tech mod and a copper ingot from another are, for crafting purposes, identical. But until now, seeing the full map of those connections required digging through obscure config files or writing custom scripts. OreDictDumper: Export Ore Dictionary to CSV/JSON changes that by turning this hidden data into clean, exportable files that anyone can read.
What Exactly Does This Tool Do?
At its core, OreDictDumper is a utility mod designed for one purpose: extracting the complete contents of the Ore Dictionary and saving them to your hard drive in a format you can actually use. The mod was originally built with wiki editors in mind — specifically, to generate data in a custom format that a MediaWiki extension could ingest automatically. Over time, the developer expanded the tool to support more universal formats, making it valuable not just for wiki maintainers but also for modpack creators, server admins, and anyone doing serious data analysis on their Minecraft installation.
The mod is deliberately lightweight. There are no new blocks, no items, no GUI screens. Everything happens through chat commands, which keeps the tool fast and unobtrusive. You install it, run a command, and get your data files in seconds.
Two Commands, Complete Control
OreDictDumper keeps its feature set focused by offering exactly two commands. This simplicity is a strength — there is no learning curve, no configuration files to fiddle with, and no way to break anything.
Dumping Everything: /dumpallores
The first command, /dumpallores, exports every single entry in the Ore Dictionary to a single file. You can specify the output format as either CSV or JSON. When the command finishes, you will find either oredump.csv or oredump.json in the root directory of your Minecraft game folder.
This command is a godsend for modpack developers. Imagine you are assembling a pack with a dozen different mods that all add their own ores. You need to know which ores overlap, which mods use different names for the same material, and where you might need to configure unification. Running /dumpallores csv gives you a complete spreadsheet of every ore tag and its associated items. You can then filter, sort, and cross-reference that data to make informed decisions about recipe adjustments and conflict resolution.
Targeted Extraction: /dumpmodores
The second command, /dumpmodores, is for when you only care about a single mod. The syntax is straightforward: /dumpmodores <abbreviation> <modid> [format]. The abbreviation is used as the prefix for the output file name, while the modid is the technical identifier of the mod you want to inspect — the same ID you see in the mod list on the title screen or in your mods folder.
If you omit the format argument, the mod defaults to the original wiki format. This is the format that started it all: a pipe-delimited string containing the tag, item name, mod ID, flags, and grid parameters. It is designed to be fed directly into a MediaWiki extension for automatic page generation. If you run a wiki for a modpack or a server, this command lets you generate complete ore listing pages in a matter of seconds, without manually typing a single entry.
Output Formats Explained
The real flexibility of OreDictDumper lies in its three supported output formats. Each one serves a different audience, and together they cover almost any use case you can imagine.
Wiki Format
This is the original format that the mod was built around. It produces lines in the structure tag!name!mod!flags!gridparams, which is compact and machine-readable. If you have a MediaWiki installation with the appropriate custom extension, you can import these lines directly and generate structured pages automatically. Even without that extension, the format is simple enough to parse with your own scripts.
CSV
Comma-separated values are the lingua franca of spreadsheet software. Open the generated CSV file in Excel, Google Sheets, or LibreOffice Calc, and you immediately get a sortable, filterable table of all ore dictionary entries. This is perfect for quick visual analysis, for sharing data with team members who are not technically inclined, or for creating reports on modpack contents.
JSON
For developers, JSON is the gold standard. The structured nature of JSON makes it trivial to parse in any programming language. You can write Python scripts to analyze your modpack, generate configuration files for other mods, or feed the data into a web-based dashboard. The JSON output from OreDictDumper is clean and well-structured, with no extraneous data to trip up your parser.
Supported Versions and Where to Get It
The developer originally targeted Minecraft versions 1.7, 1.8, and 1.9, with a commitment to keeping updates rolling out for all three branches. This is particularly valuable if you work with older, classic modpacks that have not migrated to newer versions of the game. Many long-standing community servers still run on 1.7.10 or 1.8.9, and having a modern data tool that works on those versions is a rare and appreciated feature.
One important note: the CurseForge page for this mod is no longer maintained. If you want the latest builds, bug fixes, and new features, you need to head over to Modrinth. That platform now hosts all active development, and it is the only place where you will find up-to-date releases. If you are searching for where to download OreDictDumper: Export Ore Dictionary to CSV/JSON, make Modrinth your first stop.
How to Install
Installing the mod follows the standard procedure for Minecraft mods. First, ensure you have the correct version of the mod loader installed for your chosen Minecraft version. Then, download the mod JAR file from Modrinth, matching the file to your game version. Place the JAR into the mods folder inside your Minecraft directory. Launch the game, and the mod will be active. There is no additional configuration required — just join a world or open a single-player game and start using the commands.
For those who prefer a more streamlined approach, some third-party launchers allow you to download OreDictDumper: Export Ore Dictionary to CSV/JSON for Minecraft directly from their built-in mod browsers. This can save time and eliminate the risk of downloading the wrong version.
Practical Use Cases
The scenarios where this tool shines are numerous, and they go far beyond the wiki-editing niche it was originally designed for.
- Modpack Unification: When assembling a pack with multiple tech mods, you often want all copper, tin, and silver ores to be interchangeable. Running /dumpallores csv shows you exactly which mods use which tags, allowing you to configure unification mods correctly the first time.
- Wiki Automation: If you maintain a wiki for a mod or a modpack, the wiki format output lets you generate complete ore pages automatically. No more manually typing out every ore name and its variants.
- Recipe Debugging: Have you ever wondered why a crafting recipe is not working? Sometimes the issue is that the item you are using is not registered under the tag the recipe expects. A quick dump reveals the truth instantly.
- Data Analysis: For researchers or analysts studying modding trends, the JSON output provides a rich dataset. You can analyze how many mods add the same ore, which tags are most common, and how naming conventions vary across the modding ecosystem.
- Server Administration: If you run a server with custom plugins that interact with ores, having an up-to-date dump of the ore dictionary helps you write better configuration files and troubleshoot player reports.
Final Thoughts
OreDictDumper: Export Ore Dictionary to CSV/JSON is a small utility with an outsized impact. It does not add flashy content or new mechanics, but it provides something far more valuable for serious Minecraft work: transparency. The Ore Dictionary has always been a black box, and this mod finally opens it up.
Whether you are a wiki editor drowning in manual data entry, a modpack creator fighting ore duplication, or a developer building tools around Minecraft data, this mod earns its place in your toolkit. The support for multiple output formats ensures that whatever your workflow looks like, you can integrate the exported data seamlessly. And with ongoing development on Modrinth, the tool continues to evolve. For anyone who works with Minecraft content at a deeper level, OreDictDumper is a practical, time-saving addition that delivers exactly what it promises.
