I will reconcile two CSV exports and flag missing duplicate and mismatched orders

I will compare two CSV or Excel exports and create a clear reconciliation report.

What I check:

- Matching transaction or order IDs

- Missing records in either file

- Duplicate entries

- Amount mismatches

- Basic date or status inconsistencies when the columns are available

You will receive:

- A clean Excel or CSV report

- Clear match and issue labels

- A summary of the results

- Your original files left unchanged

Before ordering, please confirm both files contain a common matching field such as order ID, transaction ID, or reference number.

This Gig is for straightforward one-to-one matching. It does not include accounting audits, refund allocation, split or partial payments, payment fees, ERP or API integration, multi-currency conversion, or manual research of missing identifiers. Please message me first if your files use different structures or complex business rules.
