Data migration and clean-up

Prepare one bounded CSV dataset, understand its columns and produce a checked target export. Each useful transformation should be explainable and reviewable.

Prepare the move, preserve the trace

The need, before the tool.

An older list may mix formats, empty fields or apparent duplicates. Automatically removing similar-looking records can discard legitimate information. The work therefore starts with mapping rules and exceptions to review.

The supplied source file is preserved as a reference. A trial on a copy reveals conversions and anomalies before the agreed export is produced. You approve the processing rules; ambiguous cases are isolated rather than guessed at.

A migration with review points

01

Before

Define the file, its volume and the expected destination.

02

During

Test the rules on a copy and record discrepancies.

03

After

Check meaningful totals and hand over the remaining exceptions.

Transform without erasing the source

01

Source

The original file stays separate from the working file.

02

Rules

Agreed normalisations are explicit, not silent.

03

Decisions

Uncertain corrections remain subject to your approval.

WHAT IS HANDED OVER

Recognisable
deliverables.

  • 01An inventory of the fields and formats encountered
  • 02A source-to-target mapping table
  • 03A documented trial and anomaly list
  • 04A checked export and processing summary
ILLUSTRATIVE SCENARIO — NOT A CLIENT CASE

What could the
journey look like?

  1. 1

    Provide an authorised export and retain a reference backup.

  2. 2

    Approve the mappings using a trial copy.

  3. 3

    Review exceptions before using the target export.

Two points to clarify.

Can every duplicate be removed?

Not without reliable rules. Similar records are reviewed against agreed criteria; uncertain cases are presented for your decision.

Do you work directly in my live system?

The proposed starting scope covers files and a trial copy. A live import requires separate agreement, authorised access and suitable precautions.
