Reading Excel Macros Without Running Them
An .xlsm is three file formats stacked inside each other, and none of them is deflate. Here is how AdaptivMapr reads the VBA project out of a workbook — deterministically, for free, and without ever executing a line — plus why a password-locked project is not encrypted and why a partial macro strip is worse than none.

Why We Removed Our SNOMED Validator
We shipped a snomed_code validator, no template ever used it, and SNOMED CT requires an Affiliate Licence. In June 2026 we deleted it. Here is the reasoning, the list of code-system validators we did keep, and the rule we now apply before adding another one.

Schema Drift, Detected From a Header Fingerprint
A partner adds a column and your nightly import silently drops a field. You can catch that with one sha256 over the normalised header row — no model, no diffing service, no schema registry. Here is exactly how /v1/layouts/drift works and where the technique stops being enough.

What a Six-Layer Matching Cascade Costs You (And What It Doesn’t)
Column matching is usually posed as an AI problem. It is mostly a bookkeeping problem with an AI-shaped tail. Here are the six layers AdaptivMapr runs, the exact thresholds each one auto-accepts at, and what each one does — and does not — put on your bill.

HIPAA-Safe CSV Import: What Schema-Only Mode Actually Does
Schema-only mode sends only column headers and up to three short sample rows — never the full file. Here is precisely what leaves your system, why so little leaving you usually means no DPA, and how the compliance posture changes when you switch to full-data mode.

LOINC Codes in CSV: Resolving Free-Text Lab Values
Lab CSVs almost never arrive with LOINC codes — they arrive as free text like "Hgb" or "Glukose nüchtern". Here is how the cascade and the loinc validator turn that free text into a coded lab result you can trust.

Rather read the reference?
The mechanics live in the docs.
Posts argue a point. If you are evaluating rather than reading, these are the pages that state the behaviour without the narrative.
