Zero-Retention Architecture

The adaptive ETL engine for messy Excel files

Upload any Excel layout, shape it to your target schema, download clean JSON or CSV. When the layout changes, WipeShift re-maps it automatically — no pipeline redesign, and your data is never stored anywhere.

Drag your Excel file here to get started

.xlsx and .xls · up to 25 MB · 10,000 rows

Processed in memory — never stored

Building a product? The same engine is an MCP server

Connect your own AI agent via the Model Context Protocol and integrate the same zero-retention transformation capability directly into your systems — no web UI required.

An ETL machine, not an Excel cleaner.

Classical pipelines break when the source layout changes. WipeShift detects the change and re-maps to your unchanged target schema — nobody redesigns anything.

Hallucination-proof AI mapping

The AI never writes code and never sees your cell values — only your file's structure. It composes a transformation pipeline from a fixed menu of ten declarative operations, and every step is validated before a single row is transformed.

Zero data retention

Your file lives in server memory for the seconds it takes to transform — never written to disk, never logged, never used for training. When the response completes, the data is gone. Hosted in the EU.

Instant fingerprint replays

Save a blueprint after converting. Next week's file with the same layout is recognized by its structural fingerprint and converts in milliseconds — no AI involved at all. 10 replays a day, free.

Trust & Privacy

Zero retention by architecture, not by policy.

There is nowhere for your data to be stored: the engine holds your file in RAM only for the seconds a request takes, then it's gone. That makes the privacy conversation with your own compliance team — GDPR, SOC 2 — short.

  • Files are processed entirely in memory — nothing ever touches a disk
  • The engine runs on a read-only container filesystem
  • No cell values in logs or in AI prompts — the AI sees structure only
  • EU hosting; blueprints store mapping recipes, never your data
