Every plot page, checked against the table. You read only the flags.

What it’s for
Four parts, plainly.

By hand, until now
They cross-checked report values against the master test table with Ctrl+F, which took about three days.

What I built
A local tool that checks SAR report Word documents against the master test table, liquid check files and daily system check plots, and flags every mismatch. The review now takes about thirty minutes.

Where it is
Live and private: an internal Windows app that runs only on the reviewer’s computer, built during my 2026 summer at UL Solutions. Version 21, the latest, runs 19 checks on every plot page; earlier versions ran 13.
Rough edges
Where it stops.
- One lab’s formatsBuilt for one lab’s report and spreadsheet formats.
- Internal onlyAn internal tool, not available to the public, so there is no download or code link here.
Honest line: the checker doesn’t approve a report. It flags, and a person still decides. Both times, three days and thirty minutes, are approximate. The story of that summer is on the UL page.
