Read, write, and convert AnimData.D2 to JSON & tabbed TXT (and vice versa).
d2animdata is a command-line program for editing AnimData.D2. AnimData.D2 is a propriety file format used by Diablo 2 to store animation metadata for characters and monsters.
d2animdata can decompile AnimData.D2 to text-based file formats, such as tabbed text and JSON (see Supported File Formats for more info). Modders can edit these files to add new animations or modify existing ones. After editing, d2animdata can compile it back to a new AnimData.D2 file.
d2animdata is written in Python. It supports Python 3.6 and above, and has been tested on Windows 10 and Ubuntu Linux.
⚠ This project is very much in Alpha. There may be several bugs. Always back up your AnimData.D2 file before using d2animdata.
To use d2animdata, you must install Python 3. Then, open a command-line shell (e.g.
cmd.exe) and enter:
pip install d2animdata
This will install d2animdata on your computer.
To view help for a command, enter:

Decompiles an AnimData.D2 file to tabbed text or JSON file.

path/to/AnimData.D2 to a JSON file.
d2animdata decompile --json path/to/AnimData.D2 path/to/my-animdata.json
path/to/AnimData.D2 to a tabbed text file.
d2animdata decompile --txt path/to/AnimData.D2 path/to/my-animdata.txt
Compiles a tabbed text or JSON file to AnimData.D2 file.
$ d2animdata compile --help usage: d2animdata compile [-h] [--dedupe] [--sort] (--json | --txt) source animdata_d2 positional arguments: source JSON or tabbed text file to compile animdata_d2 AnimData.D2 file to save to optional arguments: -h, --help show this help message and exit --dedupe Remove records with duplicate COF names --sort Sort the records alphabetically before saving --json Compile JSON --txt Compile tabbed text (TXT)
Example: Compile a JSON file to
d2animdata compile --json path/to/my-animdata.json path/to/AnimData-result.D2
Example: Compile a tabbed text file to
d2animdata compile --txt path/to/my-animdata.txt path/to/AnimData-result.D2
Supported File Formats
d2animdata supports two file formats: tabbed text (
.txt) and JSON (
Tabbed text files (
.txt) can be edited with a spreadsheet program (e.g. Excel, AFJ Sheet Edit). Diablo 2 modders should already be familiar with these files, as Diablo 2 uses tabbed text files extensively to control various aspects of the game.
d2animdata is compatible with Paul Siramy's excellent
animdata_edit program, which is another popular tool for (de)compiling AnimData.D2 to tabbed text.
JSON files (
.json) can be edited with any text editor (e.g. Notepad), though I recommend using one with syntax highlighting support (e.g. Notepad++, Visual Studio Code).
JSON has several advantages over tabbed text:
JSON files can be added to a version control system (VCS), such as Git. This allows you to keep track of changes made to a file. You can compare changes across time and revert unwanted changes.
Tabbed text files and AnimData.D2 can also be added to a VCS. However, tabbed text files are tricky to deal with, because they don't produce nice-looking diff logs when compared. Binary files, such as AnimData.D2, cannot be compared at all. On the other hand, JSON files create diff logs that are easy to read.
JSON files are easier to handle in several programming languages.
Unlike tabbed text, JSON does not suffer from tricky whitespace issues.
d2animdata can also be imported from a Python script to load, edit, and save AnimData.D2.
from d2animdata import load, dump # Load an AnimData.D2 file with open('AnimData.D2', mode='rb') as animdata_file: animdata = load(animdata_file) # animdata now contains a list of Record objects. # Iterate through each record, printing its information for record in animdata: print('COF name:', record.cof_name) print('Frames per direction:', record.frames_per_direction) print('Animation speed:', record.animation_speed) print('Trigger frames:', record.triggers) # Let's find a record named '0DNUHTH' and edit it for record in animdata: if record.cof_name == '0DNUHTH': record.animation_speed = 192 # Erase all trigger frames previously set on this record. record.triggers.clear() # Set the trigger code of frame #10 to 1 # Since frame indices begin at 0, we're actually modifying the 11th frame. record.triggers = 1 break # Save the records to AnimData.D2 with open('AnimData.D2', mode='wb') as animdata_file: dump(animdata, animdata_file)
