Quick Tool Overview

The Keyword List Cleaner takes a merged export and removes exact duplicates, then the near-duplicates you choose to treat as duplicates: casing, punctuation, plurals and word order, each a separate toggle. Match type brackets are stripped and rows can be filtered by word count, which turns a morning of spreadsheet formulas into one paste.

About the Keyword List Cleaner

Paste an export and the cleaner removes exact duplicates, then optionally the near-duplicates that differ only by casing, punctuation, plural form or word order. Match type brackets and quotes are stripped, extra whitespace collapsed, and rows filtered by word count or character length.

Every keyword export arrives dirty because it comes from several places. Keyword Planner uses one casing, Search Console another, a competitor scrape a third, and merging them produces a list where "Merino Socks", "merino socks" and "merino sock" are three rows that are one keyword. Cleaning that by hand in a spreadsheet is a morning's work with formulas; here it is one paste. The near-duplicate options are deliberately separate toggles, because whether a plural is the same keyword as its singular depends on the market you are in.

Key features of the Keyword List Cleaner

Four levels of duplicate

Exact, case-insensitive, punctuation-insensitive and plural-insensitive, each on its own toggle.

Word-order matching

"socks merino" and "merino socks" collapse into one when you want them to, and stay apart when you do not.

Match type brackets stripped

A Google Ads export gives one keyword three times in three match types. Those become one row.

Length filtering

Drop the one-word heads or the eight-word tails, depending on what the list is for.

Full removal report

Every rule reports what it removed, so a surprising drop in count is traceable.

Frequently asked questions

It depends. Google often returns near-identical results for a singular and its plural, in which case they are one target. But "sock" and "socks" can have very different intent in some markets — one browsing, one buying. Check the results pages before merging them.
