Table Accessibility Auditor

Data tables without <caption>, <th scope>, or headers associations are incomprehensible to screen readers. This tool audits each table, scores it, and injects the missing structure with one click.

Tool interface

Introduction

Screen readers announce a table cell's row and column headers so users understand context. Without proper <th scope> and associations, cells are read as isolated values. This audit restores that structure.

How it works

  • Parses each <table> and runs structural checks.
  • Scores each table and lists specific issues.
  • "Apply fixes" injects scope (position-based) and id on headers.
  • Outputs corrected markup for copy/paste.

Privacy

All parsing and fixing is local via DOMParser/XMLSerializer. No upload, no account, no API key.

Limitations

  • Assumes all <table> elements are data tables.
  • Does not auto-generate caption text or full multi-level headers maps.

FAQ

When should I use scope vs headers?

scope handles simple row/column tables; headers is needed for complex tables with multi-level or irregular headers.

Is my markup uploaded?

No. Everything runs locally.
