## Guides and help pages

- [Compare exact keys and review duplicates](https://help.smartfact.ai/feedbench/guides/compare-files): Distinguish 000017 from 17, and see why repeated keys need review.
- [Inspect JSON without rounding or running its contents](https://help.smartfact.ai/feedbench/guides/exact-json): See exact number forms and keep embedded markup as plain text.
- [Check a CSV without changing its values](https://help.smartfact.ai/feedbench/guides/inspect-csv): Confirm a semicolon layout, keep leading zeroes and download a local report and backup.
- [Check an order file against supplied settings](https://help.smartfact.ai/feedbench/guides/kitproof-context): Use the known practice mapping while keeping live KitProof permissions and records outside this check.
- [Review a column mapping and its output](https://help.smartfact.ai/feedbench/guides/mapping-preview): Use the real mapping controls, inspect the separate CSV and retain the mapping recipe.
- [Read a file refusal and check a deliberate correction](https://help.smartfact.ai/feedbench/guides/refused-csv): Understand why duplicate column names prevent a complete check.
- [Understand a missing settings check](https://help.smartfact.ai/feedbench/guides/worksteps-context): Compare an incomplete WorkSteps check with a check against explicitly supplied practice settings.
