USE CASES

When to use Batch tabular de-identification audit?

Apply one shared policy across CSV/TSV/XLSX files, then measure residual risk per file: score, simplified k, rare groups and items requiring review.

  • Prepare recurring exports for a staging environment
  • Use the same HMAC secret across sources to keep pseudonyms consistent
  • Prioritize files that remain too re-identifiable after transformation
CONCRETE EXAMPLE

Batch of 24 exports

BEFORE
24 files containing emails, birth dates and postal codes
→
AFTER
ZIP of protected copies + per-file score and minimum k + review report

Your data stays in the browser

Processed content is not uploaded to WorkToolset. Required libraries may be loaded by the site, but the file stays in the browser.

GOOD TO KNOW

Limitations to know

  • Initial maximum: 50 files and 750 MB combined.
  • Batch policy is automatically derived from detected categories; ambiguous cases or fine per-column rules should be handled in the FREE + PRO single-file tool.
HOW IT WORKS

A straightforward workflow.

  1. 1Prepare the required input and choose useful options.
  2. 2Review previews, warnings and limitations before export.
  3. 3Download a new copy or report: the original stays unchanged.
