AI CSV import — AI mapping you can actually trust

AI CSV import uses a model to help turn a messy spreadsheet into clean, mapped records — matching columns to your fields, suggesting types and flagging suspect values. Mildport does this, but with a deliberate stance most “AI importers” don’t take: deterministic first, AI only where it earns its place, and explainable either way.

The problem with “AI maps your CSV” as a headline is that pure-AI mapping can give different answers on the same file, and you can’t see why it chose what it chose. For import — where a wrong mapping silently corrupts your database — that’s the opposite of what you want.

How Mildport approaches AI import

1. Deterministic matching does the bulk of the work. An explainable matcher scores header and value matches. Same input, same answer, with visible scores. See How it works.
2. An evidence-gated AI judge handles the uncertain tail. Only the columns the deterministic pass is genuinely unsure about go to the model — and only when there’s evidence to act on.
3. You bring your own model. Point it at the model you trust; it’s off by default.
4. A human confirms. Suggestions land in a review grid with the rationale shown, so a person approves before anything is applied. Confirmation is the gate, not an afterthought.

	Typical “AI importer”	Mildport
Default behaviour	AI maps everything	Deterministic first; AI off by default
Determinism	Can vary run to run	Same input, same answer
Explainability	Opaque	Visible scores + AI rationale in the grid
Model	Vendor’s	Bring your own
Data path	Through vendor cloud	Self-hosted; you control where AI calls go

Beyond column mapping: AI on hard documents

The same evidence-gated approach extends to the inputs that break ordinary importers — PDF tables and scanned, OCR’d documents — where AI helps extract structured facts from unstructured files, again with the human as the gate. Mildport decodes these through dedicated sidecars rather than assuming clean CSV.

Why this matters

You get the convenience people want from “AI import” — fewer columns to map by hand, smart suggestions on the messy ones — without giving up determinism, auditability, or control over where your data and your model live. For a deeper look at just the mapping step, see automatic column mapping.

FAQ

What is AI CSV import? Using a language model to help interpret a messy CSV — matching columns to your fields, suggesting types and flagging wrong-looking values — so a person doesn’t map every column by hand.

How does Mildport use AI for imports? Deterministic first (explainable matcher, same input → same answer), with an optional evidence-gated AI judge for the uncertain columns only. Bring your own model, rationale shown, off by default.

Is AI-based CSV import reliable? Pure AI mapping can be non-deterministic and hard to audit. Mildport keeps AI to the uncertain tail, gates it on evidence, and has a human confirm before applying.

Does my data leave my infrastructure when using AI import? Mildport is self-hosted and you bring your own model, so you control where AI calls go. Wire it to a model in your own environment and no import data needs to leave your infrastructure.
