This is the real content of our free sample pack (10 tools). For full file upload with drag-and-drop, use the Validator tool, which runs the same parsing plus structural checks.
How it works
The .btx container is XML
A Bluebeam Tool Chest export is a plain XML document. The viewer reads the outer structure — the Tool Chest title, every ToolChestItem, its Name, Type and Resources — without needing Revu installed.
Tool payloads are compressed streams
Each tool carries hex-encoded, zlib-deflate compressed appearance streams (PDF XObjects) and measure dictionaries. The viewer shows you where they sit and how large each payload is.
Nothing leaves your browser
Parsing happens entirely client-side with the browser-native DecompressionStream API. Your file is never uploaded, stored or sent to a server.
Who uses this tool
Estimator reviewing a downloaded pack
Checking a purchased tool set before importing it
Before: Import blindly and hope the tools appear in the Tool Chest.
After: Open the file here first, see the tool count, types and structure, then import with confidence.
BIM manager auditing a team library
Documenting what the company tool set actually contains
Before: No easy answer to "what exactly is in our standard tool set?"
After: Read the full structure in the browser and record it in your library documentation.
Contractor learning BTX files
Understanding the Tool Chest file format
Before: The .btx format feels opaque — a binary blob from Revu.
After: See the readable XML structure and learn how tool sets are assembled.
Support agent helping a customer
Diagnosing why a file will not import
Before: Ask the customer to reinstall Revu and try again.
After: Have them open the file here — if the structure is broken, that shows in seconds.
Developer building tool set tooling
Understanding the format before writing scripts
Before: Reverse-engineer the format from scratch.
After: Read real structure and payload layout immediately, then use the JSON converter for scripted work.
QA reviewer signing off a pack
Verifying a delivered tool set matches its spec
Before: Import into Revu and manually check each tool.
After: Quickly verify tool count, naming pattern and types in the browser before opening Revu.
