Company Normalizer grouping spelling variants of the same company in a CSV column

One company, five spellings

Account lists accumulate spelling drift: someone types ACME Inc, an import adds Acme, Inc., a form submits acme incorporated. Reports then split one customer's revenue across three "companies". This tool tidies every name (spacing, punctuation, legal suffixes) and groups spellings that differ only cosmetically, unifying each group to its most common form — with a report of every merge so nothing happens silently.

The variants this can't see

Text comparison can't know that Acme and Acme Industrial — or IBM and International Business Machines — are the same account. Grouping those takes semantic matching: that's SmartMatch, which is why it's the paid half of this job. Run a free CleanSmart check to see what it finds in your account list, or dedupe the rows once the names agree.

Frequently asked questions

What counts as a variant of the same company?

Spellings that differ only in capitalization, punctuation, spacing, the word “the”, or the legal suffix — ACME Inc, Acme, Inc., and acme incorporated group together. The most frequent spelling in your file becomes the suggested canonical name.

Will it merge Acme with Acme Industrial?

No. Those differ by a real word, and deciding they're the same company takes semantic matching — understanding meaning, not just text. That's SmartMatch in CleanSmart, which catches variants no text comparison can.

What does the cleaned file contain?

Every company name gets its whitespace, trailing punctuation, and legal suffix tidied (inc → Inc., llc → LLC). With Unify variants on, rows in a variant group are rewritten to the group's canonical spelling. The variants report lists every group so you can review the merges.

Is my customer list uploaded anywhere?

No — grouping happens in your browser tab. The first 5,000 rows are processed; larger files keep their remaining rows unchanged in the download.
