Who this is for

Security: who benefits

Finance, accounting, bookkeeping, and operations teams evaluating spreadsheet reconciliation software.

Teams that treat uploaded CSV and Excel files as sensitive operational data.

Reviewers who need clear matched, unmatched, and audit-trail outputs.

Manual workflow in Excel

How teams handle security today

Keep source exports unchanged and compare them in a dedicated workflow.

Limit sharing of raw spreadsheet files to people who need reconciliation access.

Use matched/unmatched exports and audit trail details for review instead of hidden workbook logic.

Where manual reconciliation breaks

Common security failure points

Manual reconciliation often depends on copied formulas, edited source files, and undocumented assumptions.

Reviewers can lose time reconstructing why a row was matched, grouped, or left unresolved.

Spreadsheets can be shared too widely when output and source files are not clearly separated.

How FireLookup handles it

A clearer security workflow

FireLookup keeps the workflow focused on upload, matching rules, review, and export.

The product avoids fake claims on this site and describes only the capabilities currently positioned publicly.

Uploaded CSVs should be treated as sensitive data, and retention controls are part of the product roadmap and settings.

Workflow

Step-by-step reconciliation flow

  1. 01

    Upload File A and File B without changing the source exports.

  2. 02

    Choose amount columns, matching keys, and the relationship types to test.

  3. 03

    Review matched, unmatched, and grouped results before exporting the reconciliation output.

FAQ

Common questions

Practical answers for finance and operations teams evaluating this reconciliation workflow.

Does FireLookup change my source files?

No. The workflow compares uploaded files and produces review output; your source exports should remain unchanged.

Should uploaded CSV files be treated as sensitive?

Yes. Treat reconciliation uploads as sensitive finance or operations data and share exports only with the right reviewers.

Is there an option to delete stored uploaded files later?

FireLookup has retention settings for runs, and an auto-delete option for stored uploaded files remains a TODO where deeper storage is added.
