v0.1.0 — Read-only XLSX print diagnostics

First public release of the read-only XLSX print diagnostic tool.

Open Printscope · 中文说明

Included

• Separate declared, stored, populated and candidate-visible cell bounds.
• Evidence for explicit hiding formats, white fonts, print areas, page breaks and distant drawing anchors.
• Local, cancellable workbook inspection and metadata-only JSON reports.
• Bounded ZIP/XML handling, 25 automated tests and real browser screenshots.

The actual sample workbook has 13 stored cells and two findings, including a value at M85 hidden by ;;;. Download it from the app to inspect the setting yourself.

Run and verify

The source archives below contain the app and inspection core, not a desktop installer. Use Node.js 22.13+, run npm ci, then npm run dev, or use the hosted tool.

Tests and the Linux build/Pages deployment passed. The public sample and issue form were checked. See verification notes for gaps.

No formula calculation, exact page count or automatic repair. Candidate-visible bounds are not a replacement print area. Report a finding using a fresh workbook with invented values, never private data.
