Python NBT Data and Log Parser + Extractor (nbtdatparse.py)

scanning non-corrupt .minecraft with nbtdatparse-v3.py

scanning 20,000+ recovered .dat files with older nbtdatparse version (will update this photo soon) This script scans minecraft data and log files for minecraft seeds. My use case is finding the seed to my minecraft world I deleted 13 years ago. I also wiped the drive at least once :)

• Short guide for DMDE minecraft .dat / .log.gz file recovery using scan signatures. (DMDE is free software that can recover up to 4000 files, one directory at a time)
• what is a level.dat file

nbtdatparse.py retrieves:

• file name
• seed
• playtime
• generator used
• level name
• game mode
• spawn location
• file path
• version
• last played
• searches logs for instances of 'seed'

0. Download my .py file

place file in good location

1. Install Python

3.8 and 3.11 worked for me, each on a seperate machine

2. Install Required Libraries

install the libraries to the interpreter / version of python that runs the code

• nbtlib

  pip install nbtlib
  

• openpyxl

  pip install openpyxl
  

3. Set directory_path for scanning and output of minecraft_worlds_recovery.xlsx - not optional

• current examples: D:/dump & C:/Users/juke32/AppData/Roaming/.minecraft/saves

4. Should be good to run!

If it doesn't work double check the file path, direction of the slashes, if the correct python interpreter is used, try using a terminal window not an ide or coding enviroment.

5. Sorting through the .xlsx in excel

1. Highlight the top title row of the data in any tab

• Click sort and filter
• Select filter

2. The top row should now have dropdown arrows, select and sort however you need
3. If you uncheck errors/seeds/info you already know about, you can reduce the clutter I didn't code out
