FAQ

Scope, limits, and where officelens fits next to the tools you already use.

Questions

Are my documents uploaded anywhere?

No. The CLI has no network code, and the playground runs the same bundled rules entirely in your browser tab. No file, or any part of one, is transmitted.

Does it need Word, PowerPoint, or a JVM?

No. officelens opens the OOXML zip and parses its XML directly. There is no Office installation, no headless renderer, and no Java runtime.

What do the exit codes mean?

0 when nothing meets the threshold, 1 when findings meet --fail-on (default error), 2 for invalid usage or a package that cannot be parsed as OOXML, and 3 when an input or the report could not be read or written.

Can I gate a pull request on it?

Yes. Use the exit codes for a simple gate, or emit SARIF and upload it with github/codeql-action/upload-sarif so findings appear as code-scanning annotations.

Does it replace the Microsoft Accessibility Checker?

No. It complements it. The Microsoft checker is a GUI with no CLI or JSON; officelens runs headless in CI and emits machine-readable output. Neither replaces a human review.

Does it cover spreadsheets?

Not yet. The current rule set targets DOCX and PPTX. .xlsx support is out of scope for now.

Limitations

Static analysis only

officelens is static XML analysis: it reads the parts directly rather than rendering them, so it cannot compute colour contrast. Not every WCAG success criterion is machine-checkable, so it covers the structural, high-signal failures that block assistive technology. Spreadsheets (.xlsx) are not covered yet.

How it compares

Microsoft Accessibility Checker
Windows, macOS, and web only. No CLI, no JSON, and no presence on a Linux CI runner, so it cannot gate a pull request.
Accessr
Covers .docx only. No CLI and no JSON, so it cannot sit in a pipeline or gate a pull request. accessr.net
Schema validators
ooxml-cli, xarsh/ooxml-validator, and openxml-audit check schema and well-formedness only, with no WCAG semantics.
ez-a
A roughly zero-star Python GUI limited to PPTX alt text. No batch mode and nothing to script against.
officelens
Open source, offline, cross-platform, and scriptable. The CLI and the browser playground run the same rules, and both emit machine-readable output for CI. github.com/srivtx/officelens
