Fixing Common Errors in NM FindDuplicates

While “NM FindDuplicates” is not a standard standalone industry software name, this exact phrasing typically maps to a beginner-oriented guide for finding and managing duplicates using specific automation tools, data management practices, or custom scripts (such as custom Excel VBA macros, or specialized data cleaners like the Salesforce FindDuplicates API Class and NM Collector Software inventories).

Because clean data is vital, here is the universal, step-by-step framework tailored for beginners to find and manage duplicates across the most common tools where this logic is applied. Step 1: Prepare and Back Up Your Data

Never attempt to remove duplicates on your only active file.

Create a backup copy of your dataset or database before executing any duplicate detection.

Ensure uniform formatting by removing trailing spaces and ensuring matching columns (like text or numbers) share the same data type. Step 2: Set Your Match Criteria

Decide exactly what constitutes a “duplicate” in your system.

Exact Matches: Every single column or field in the row matches another row exactly.

Partial/Key Matches: Only specific fields match (for example, two different entries that share the exact same Email Address or ID Number). Step 3: Execute the “Find Duplicates” Function

Depending on your platform, you will use the built-in system tools: Option A: In Microsoft Excel (The Most Common Method)

Highlight the target dataset range using your mouse or keyboard shortcuts. Navigate to the Home Tab on the top ribbon.

Click on Conditional Formatting -> Highlight Cells Rules -> Duplicate Values.

Choose your preferred color fill and click OK to instantly view duplicates highlighted in red or yellow.

Option B: In Enterprise Data / CRM Platforms (e.g., Salesforce Datacloud APIs)

Use the FindDuplicates Class array rules to execute a rule-based search across your records.

The system evaluates input objects against active matching rules to generate a filtered list of overlapping data.

Option C: In Dedicated Inventory Software (e.g., NM Collector Systems) Open your customized collection template or home inventory. Sort your items by Identification or Serial Number columns.

Manually filter or use the native grid finder to isolate duplicate inventory logs. Step 4: Review and Merge/Delete Safely

Isolating duplicates is safe, but removing them requires verification. Find Duplicates Merge UI – OneMerge
