Validate a CSV and Source-File Expense Handoff

Practical answer: Check record counts, currencies, filenames and source links before sending an expense export to another system.

A successful download does not prove that an export is complete. Rows can be missing, dates can change format and source filenames can lose their relationship to the spreadsheet.

Reconcile the selected scope and row count

Record the filter, date range and statuses used for export. Compare the resulting row count with the reviewed set and separate excluded exceptions deliberately.

Inspect fields that commonly change between systems

Check headers, encoding, dates, decimal separators, currency codes, negative values and empty fields. Reconcile totals by currency rather than adding unlike amounts.

• Open rows near the beginning, middle and end.
• Test several source-file references.
• Confirm ZIP contents match exported rows.

Send a short handoff note

Describe scope, file structure and unresolved exceptions so the recipient knows what the package contains and what it does not claim to complete.

Export validation gate

• Filter scope and row count agree.
• Dates, amounts and currencies preserve meaning.
• Sample source files open from the package.
• Exceptions and exclusions are documented.

Questions people ask in this situation

Is one grand total enough to validate the export?

No. Reconcile by currency and review row-level meaning because mixed currencies or signs can produce misleading totals.

Should source files use spreadsheet row numbers?

Use a stable reference that survives sorting and import rather than relying only on the current row position.
