Data cleanup

Clean data, usable systems.

We turn messy spreadsheets, exports, and shared-drive sprawl into reliable data your team can trust.

DeduplicationNormalizationFile migrationDatabase repair

bytespell cleans the practical mess around business data: inconsistent formats, duplicate records, unclear ownership, and review processes that live in side conversations. The result is cleaner source material and software that keeps it clean.

Typical work

  • Messy spreadsheet consolidation
  • File and record classification
  • Human-in-the-loop review portals
  • Data QA dashboards and exports
  • SQL database cleanup and reshaping
  • File migration planning and validation

Good fit

When this helps

  • The same customer, file, or record appears in multiple places with different values.
  • A spreadsheet became operational infrastructure and nobody trusts it anymore.
  • You need a clean source of truth before migration, reporting, or automation work.

Approach

How we shape it

  1. 1Profile the current files, tables, exports, and edge cases before touching the data.
  2. 2Define cleanup rules and review points so automation does not hide judgment calls.
  3. 3Deliver cleaned data, validation notes, and a path for keeping the system clean.

Examples

What we can build

Records

Spreadsheet rescue

Combine duplicate tabs, standardize fields, and flag questionable rows before they move downstream.

Files

File classification workflow

Turn shared-drive sprawl into reviewable categories with notes, confidence, and exportable decisions.

Migration

File migration plan

Map old folders, naming patterns, and metadata into a cleaner structure before anything gets moved.

Database

SQL cleanup pass

Untangle inconsistent tables, old columns, duplicate rows, and exports that need to become reliable again.

Operations

Data quality dashboard

Track missing values, duplicates, cleanup progress, and the records that still need a human call.
