01
Check the need
Excel remains suitable for many tasks. A move becomes worth considering when several people need to update the same information, connect lists or track work stages with different access rights. Migration alone will not solve duplicate records or inconsistent definitions.
Before choosing the destination, list essential uses: data entry, viewing, reporting, automation and exchange with other systems. Identify who owns the data and who will maintain it.
02
Prepare the data
Inventory the files and columns people actually use. Give each field a name, format and rule for completion. Separate different entities, such as contacts, companies and enquiries, then decide how to connect them without relying only on their display names.
Resolve duplicates, missing values and ambiguous dates before import. Identify formulas, attachments, filters and macros too: their behaviour must be checked or rebuilt. Keep a dated copy of the original files.
03
Test a sample
Import a representative set first: complete rows, missing data, duplicates, accented characters and unusual cases. Compare record counts, fields, relationships and calculated results with the source. Ask users to perform their normal tasks in the test base.
Check access before inviting everyone. Viewing, editing and changing the structure are different permissions. If a critical use fails the test, adjust the model before moving the rest of the data.
04
Plan the changeover
Choose a transfer window, appoint an owner and announce when changes to the old files will stop. Without that rule, data can change in Excel after it has been copied and disappear from the new workflow.
Prepare a rollback procedure: who triggers it, which copy to restore and how to handle work entered in the meantime. Keep the old files read-only until checks are complete.
05
Check the result
Compare totals and a sample of records after the move. Monitor input errors, denied access and connected automations. Resolve discrepancies before declaring the old file obsolete.
- Document uses and data owners.
- Clean and back up files before import.
- Test relationships, calculations and permissions.
- Plan an explicit changeover and rollback.
