uasset-dt-to-json

Parses UAsset files with embedded DataTables and dumps the contents to JSON. Tracks byte offsets to allow easier hex editing.

Heavily based off of UAssetParser.

This script is most definitely a work-in-progress. Not all property types are supported, and not all those that are supported are 100% correct in all cases. Pull requests welcome.

Usage

JSON output is printed to standard out. It can and will quickly overflow the terminal scrollback buffer, re-directing to a file is basically mandatory.

usage: datatable-to-json.py [file]

Dump UAsset DataTable to JSON

positional arguments:
  file           Input UAsset file

optional arguments:
  -h, --help     show this help message and exit
  --no-names     Do not dump name table
  --no-data      Do not dump exported data
  --values-only  Only print values, not offset/length information

Example output:
