I need a small yet reliable tool that inspects AutoStore floor-elevation survey files and flags every point that drifts outside the limits I supply. Python is my first choice, but I can work with a well-structured Excel or LibreOffice macro if that speeds things up. Scope • Read one or more raw survey files (CSV or XLSX—happy to confirm exact layout with you). • Let me upload a separate “rules” file that holds all custom tolerances and other limits. • Compare each elevation value against those limits and mark pass/fail for every surveyed point. • Produce a clear compliance table (OK / out-of-spec) plus a concise summary figure I can paste into reports. • Keep the validation logic modular so I can swap in new rule sets without touching the core code. What I’ll need from you • Fully functioning script or macro, cleanly commented. • Simple README with setup steps and an example rule file. • Quick hand-off call or video to walk through the workflow and answer questions. Nice-to-have (if you see quick wins) • Command-line switch or button to export a filtered list of failures only. • Config file for default paths and column names. If you’re comfortable parsing survey data and turning specs into dependable validation code, let’s get started.
