01 / Do it yourself

From zero to working.

Read the complete sequence before starting. Use a test account or non-production copy whenever the workflow touches important business data.

  1. 01
    STEP 1

    Open a copy in a plain-text-aware editor and confirm UTF-8.

  2. 02
    STEP 2

    Check headers, delimiters, and required key columns.

  3. 03
    STEP 3

    Count blank keys and duplicate keys.

  4. 04
    STEP 4

    Test ten representative rows in a non-production import.

Useful guardrails.

Never test first in production

Watch dates like 04/05/2026

Preserve leading zeroes

Reconcile rejected rows
