Built for requirements review work
PMO / project control
Compare the requirements baseline before and after a review cycle, then isolate added, removed and changed IDs before the next status or steering review.
Business analyst
Check stakeholder revisions at field level and ignore administrative columns such as updated_at when they are not part of the requirement decision.
QA / test lead
Use the changed-requirement list to focus regression-impact review instead of rereading every unchanged row in the specification.
Consultant
Compare client-provided CSV/TSV baselines locally in the browser and export the resulting diff CSV for a structured review handoff.
ReqDelta reports source differences; it does not decide requirement quality, test coverage or approval status for you.
When ReqDelta is the right fit
ReqDelta sits between a generic table diff and a full requirements-management platform. Use the smallest tool that matches the job.
| Need | Generic CSV diff | ReqDelta | Enterprise requirements management |
|---|---|---|---|
| Compare arbitrary tabular data | Best fit | Possible, but not the focus | Usually unnecessary |
| Review requirements/specification baselines by stable ID | Possible, but generic | Best fit | Also supported |
| Keep client or project CSV/TSV local with no account | Depends on the tool | Built for this | Usually workspace-based |
| Traceability, approvals, collaboration or dependency management | Not designed for it | Not designed for it | Best fit |
Choose ReqDelta when: your requirements already live in Excel, CSV, an export from another system, or a client deliverable, and you need a fast deterministic baseline review without migrating the project into another platform.
