Use cases
These are the real jobs people hire Sigmera to do — preparing a messy spreadsheet for an import, deduplicating leads, tidying candidate data. Each guide walks you through the exact steps for that scenario, using tools that run entirely in your browser. Nothing is uploaded, so it’s GDPR-safe by design.
