Customer Relationship Management (CRM) systems are the lifeblood of many businesses. However, their value is only as good as the data they contain. Dirty data, such as duplicate records and inconsistent entries, can lead to missed opportunities, poor customer experiences and wasted marketing spend.

The Problem: Siloed and Duplicate Records

Consider a typical scenario: A company receives a list of new leads from a recent marketing campaign. Before importing these leads into their CRM, they need to ensure they are not already existing customers or duplicate entries. However, account names are often entered inconsistently, making exact matching impossible.

For example, a new lead might be listed as "Acme Corp", while the existing CRM record is "Acme Corporation". A traditional exact-match lookup would fail to identify this as the same company.

The Solution: Flookup and Google Sheets

Flookup Data Wrangler provides a powerful and easy-to-use solution for cleaning and matching CRM data within Google Sheets. By leveraging fuzzy matching and text normalisation, you can quickly identify and resolve inconsistencies that other tools miss.

Step 1: Normalise Account Names

The first step is to standardise account names. Flookup's NORMALIZE function can automatically remove irrelevant punctuation and common suffixes (like "Inc" or "LLC"), ensuring a more consistent baseline for matching.

=NORMALIZE(A2, {"Inc","LLC"}, , "text")

Step 2: Fuzzy-match New Leads to Existing Accounts

Once account names are normalised, you can use Flookup's FLOOKUP function to perform a fuzzy match between your new leads and your existing CRM records. This allows you to find matches even when there are slight variations in spelling or formatting.

=FLOOKUP(B2, ExistingAccounts!A:B, 2, FALSE, 0.85)

In this example, Flookup will search for the normalised account name from cell B2 in your existing accounts list and return the matching account ID for any match with a similarity score of 85 per cent or higher.

By implementing Flookup into their CRM data cleaning workflow, businesses can achieve significant benefits:
