Why teams use FireLookup

A cleaner, faster workflow for spreadsheet reconciliation.

How to reconcile Excel and CSV files automatically

To reconcile spreadsheets automatically, upload two files, choose the columns that should line up, and run exact or fuzzy matching rules. FireLookup then shows matched and unmatched rows before you export the result. That workflow gives finance and operations teams a faster way to compare two spreadsheets, handle CSV matching in the browser, and keep the review process consistent.

Spreadsheet reconciliation software for finance teams

FireLookup is spreadsheet reconciliation software built for finance and operations teams that need repeatable close and exception-review workflows. Teams use it to match bank statements to ledgers, reconcile invoices to orders, and compare exported reports from different systems. It supports CSV, XLSX, XLSM, ODS, and Numbers files, so teams can keep one process even when source systems export different formats.

Audit-ready reconciliation with a full audit trail

Every reconciliation run records a timestamped audit trail with reconciliation keys, matched rows, and exceptions that still need attention. Teams can export audit-ready results for reviewers, auditors, or downstream handoffs. Because matched and unmatched rows stay visible in the same workflow, it is easier to explain why records were paired, grouped, or left unresolved.
