Validate Bluebeam BTX Tool Chest Files Before You Import
Free browser validator that checks BTX structure, tool names, resource IDs, hex payloads and deflate decoding — catch broken tool sets before Revu import.
Pre-loaded with a real 10-tool sample pack. No account, no upload — files are read locally in your browser.
Try it now
Drop a .btx file here, or click to choose
Your file is read in your browser only — nothing is uploaded or stored.
How it works
Nine structural checks, run instantly
The validator verifies the XML document type, root element, format version, tool entries, names, resource IDs, hex payload validity and full deflate decoding of every tool — the same failure modes that stop a Revu import.
Errors vs non-fatal warnings
Errors mean the file will not import cleanly or is corrupt. Warnings mean the file will import but is missing optional metadata you may want to fix in the source tool set.
Client-side only
Validation runs in your browser with the native DecompressionStream API. Your file is never uploaded, stored or transmitted.
Who uses this tool
Contractor importing a downloaded tool set
Pre-import check after downloading a pack
Before: Import fails silently or Revu shows a vague error.
After: Run the file through validation first and see exactly which structure is broken.
IT admin deploying team tool sets
Verifying a master library before rollout
Before: Roll out to the team and wait for individual reports of broken imports.
After: Validate the master file once, confirm zero errors, then distribute with confidence.
Tool set author testing an export
QA on a freshly exported .btx file
Before: No feedback loop between exporting and knowing the file is sound.
After: Export, validate in seconds, iterate — before the file ever reaches a colleague.
Support agent diagnosing import problems
Triaging "my tool set won't import" tickets
Before: Blind guessing between file corruption and Revu configuration.
After: Ask the customer to validate the file here — the result immediately localises the fault.
Consultant receiving client tool standards
Onboarding a new client markup standard
Before: Import unknown files from unknown sources into production Revu.
After: Verify structure first, then import — a clean audit step for every external file.
Trainer teaching Revu workflows
Demonstrating how Tool Chest files are structured
Before: No visible way to show students what a good vs broken file looks like.
After: Project the validator, show pass and fail states, teach the format in minutes.
