Find Clarity in the Clutter.

Clean data. Clear direction. DupliFox is your matching assistant for messy spreadsheets — normalization-first, fuzzy-matching second, with every flagged match showing exactly why it matched. Upload, review, and export clean data in one place.

Why DupliFox is different

Simple dedup tools often stop at an exact-text match, which catches almost nothing, or run everything through a single fuzzy-matching pass. Neither handles the messy reality of business data well.

Normalization first, fuzzy matching second. Before DupliFox calculates a similarity score, it standardizes common variations like “Ave” and “Avenue,” “LLC” and “Inc.,” and inconsistent casing and whitespace. Those obvious matches are caught by clear rules, not left to a fuzzy score that might land just below your threshold.

You see why, not just what. Many tools hand you a similarity percentage and nothing else. DupliFox shows whether each match was exact, normalized, or fuzzy, so you can trust the confident matches and look harder at the uncertain ones.

Built for the whole workflow, not just detection. Inline review, bulk actions, and per-match choices (keep A, keep B, or Smart merge, which fills blank fields from the other record) let you clean things up right in your browser instead of exporting a list and doing the real work elsewhere.

What DupliFox can do

  • Smart duplicate detection: catches exact and near matches, not just identical text

  • Address and company-name cleanup: recognizes “Ave” = “Avenue” and “LLC” = “Inc” before fuzzy scoring

  • Phone and email matching: in columns labeled Phone or Email, phone numbers match regardless of formatting, and emails match regardless of capitalization or common domain typos like “gmial.com”

  • Find duplicates inside one file: groups three or more copies of the same record and suggests keeping the most complete one

  • Smart merge: fills blank fields from the duplicate instead of forcing you to pick one record wholesale

  • Match transparency: every flagged match shows whether it matched exactly, after normalization, or by fuzzy score

  • Compare against multiple reference files in a single run

  • Import templates: pre-filled column mapping for Salesforce, HubSpot, QuickBooks, Mailchimp, and Google Contacts exports, or map any spreadsheet yourself

  • Automatic column labels: if a column has no header, DupliFox suggests one (like Email or Phone) based on what’s in it, and you can accept or change it

  • Inline review, right in your browser: accept, reject, or choose which record to keep

  • Bulk actions, plus optional auto-accept for high-confidence matches

  • Saved matching profiles: save your column mapping and settings and reuse them

  • Audit log: download a record of exactly what changed

  • Clean export: download your deduplicated results as a spreadsheet

Your data stays yours

We know what you’re uploading — customer lists, account records, contact databases. It’s sensitive, and it’s yours. We process it, then we let it go. Your spreadsheet is used only to run the comparison you asked for. We don’t keep a copy, back it up, browse through it, or use it for anything else. It’s automatically deleted from our systems within a few hours of your session ending, at the latest.

We never see your card number. Payment is handled entirely by Stripe, a payment processor trusted by millions of businesses. Your card details go straight to Stripe and never pass through our servers.

Nothing is sold or shared. We don’t sell your data, share it with advertisers, or use it to train anything. Your file is kept only while you’re working with it, plus the short cleanup window described above, then deleted automatically.

You’re always in control. By default, every match we flag is a suggestion. You decide what gets merged or removed, one record at a time or in bulk. Cancel any time, and your access continues through the end of your paid period.

DupliFox is built for business contact and account data. Please don’t upload health records, Social Security numbers, or payment card numbers; our Terms don’t allow it.
