## Guides and help pages

- [Distinguish exact codes and absent values](https://help.smartfact.ai/findbench/guides/exact-and-missing): Leading zeroes and spaces remain exact; unlisted codes never imply no stock.
- [Load a file and read every matching row](https://help.smartfact.ai/findbench/guides/load-and-lookup): Review actual CSV mapping, duplicated rows, two locations and conflicting descriptions.
- [Keep missing locations explicit](https://help.smartfact.ai/findbench/guides/missing-location): A listed row with no location stays visibly incomplete.
- [Refuse a bad file and replace deliberately](https://help.smartfact.ai/findbench/guides/replace-and-refuse): Keep accepted work after a refusal, then invalidate the old result by loading a new snapshot.
- [Look up a location in reverse](https://help.smartfact.ai/findbench/guides/reverse-lookup): Read every code row your file lists at an exact rack.
- [Export and recover the real reference](https://help.smartfact.ai/findbench/guides/save-and-restore): Download real CSV, PDF and project files, save an isolated copy, and restore or refuse backups.
