Code cleanup & fixes

Automatic cleanup (always on)

Before any comparison, every code — from your catalog, your baseline file, or a scanner — goes through the same cleanup:

1. Trim spaces from both ends
2. Uppercase — abc123 becomes ABC123
3. Drop leading zeros on all-digit codes — 000123 becomes 123 (all-zero codes stay 0)

The mobile app cleans scans the same way, so a shelf scan matches your imported catalog with zero configuration.

Fix-up rules (only during import)

Sometimes the codes in your file differ from what's printed on shelf labels — the classic case is a check digit or a fixed prefix in the master file. Fix-up rules handle this: they're set in the import template, run only during import, and change the stored value.

Available operations

Operation	What it does
dropFirst	Remove the first character
dropLast	Remove the last character
takeMiddle	Keep a middle section

You can chain up to 5 operations, applied in order.

Conditions

Each operation can carry conditions — it only runs when all of them hold:

• Length: lengthGt / lengthGe / lengthEq / lengthLe / lengthLt
• Content: startsWith / endsWith / contains

Conditions are checked against the value as it is at that step in the chain.

Example — drop the check digit only from 14-digit codes:

op: dropLast, if: lengthEq(14)

What the mobile app does

Just the automatic cleanup — nothing more. What the scanner sees is what gets submitted. Fix-up rules are an import-time, server-side thing only. When the app looks up a scan, it uses the cleaned-up code and follows your match order.
