What is a CSV lead cleaner?
A CSV lead cleaneris software that takes a messy spreadsheet of sales leads and standardises the data — normalising names, formatting phone numbers, validating emails, and removing duplicate rows. The output is a clean, structured list that's ready for follow-up or for import into a CRM like HubSpot, Salesforce, or Pipedrive.
Lead Sorted is an AI-powered CSV lead cleaner. It runs every row through a language model so it can extract structured fields even from CSVs with missing headers, free-text rows, or merged columns.
Who Lead Sorted's CSV cleaner is for
We built it for the messy-spreadsheet moment, not for enterprise data engineering.
- Small sales teams whose leads live in spreadsheets
- In-house teams overwhelmed by inbound CSVs from ad campaigns
- Service businesses, including mortgage brokers, contractors, and home services crews
- Freelance lead-gen marketers cleaning lists for clients
- Founders who want a CRM-ready CSV before adopting HubSpot or Salesforce
- Teams that need pipeline forecasting, quotas, or account hierarchies (use Salesforce / HubSpot Enterprise)
- Marketing automation, drip emails, or lead scoring beyond hot/warm/cold
- Bulk B2B data enrichment from public sources (use Apollo, Clay, or ZoomInfo)
- Million-row data engineering jobs (use OpenRefine or a purpose-built ETL tool)
How to clean a messy lead CSV
Four steps. Total time: under two minutes for a few hundred leads.
Step 1
Upload the messy CSV
Drag a CSV, paste an Excel sheet, or copy rough notes. Headers can be missing, columns can be in any order, rows can be incomplete — Lead Sorted reads what you have.
Step 2
Let AI extract and normalise
AI pulls out each lead's name, phone, email, source, and intent — even from free-text rows. Phone numbers get normalised (E.164), emails validated, names cased correctly.
Step 3
Review duplicates & missing fields
Duplicates by email or phone get flagged for one-click merge. Rows with no contact method are surfaced for review. Junk rows ('not a lead') are filtered automatically.
Step 4
Export a CRM-ready CSV
Download a standard-format CSV ready for HubSpot, Salesforce, Pipedrive, or Zoho. Or keep your leads inside Lead Sorted's follow-up workspace.

CSV lead cleaner FAQ
Direct answers to the questions sales teams ask before uploading.
What is a CSV lead cleaner?
A CSV lead cleaner is software that takes a messy spreadsheet of sales leads and standardises the data — normalising names, formatting phone numbers, validating emails, and removing duplicate rows. The output is a clean, structured list that's ready for follow-up or for import into a CRM like HubSpot, Salesforce, or Pipedrive.
How do I clean a lead list before importing to a CRM?
Upload your CSV to Lead Sorted, let the AI normalise contact fields and detect duplicates, review the flagged rows, then export a CRM-ready CSV. Total time is usually under two minutes for a few hundred leads.
How does Lead Sorted detect duplicate leads?
Lead Sorted matches duplicates by normalised email and phone number. Slight name variations (e.g. ‘Mike B’ and ‘Michael B.’) are surfaced as possible duplicates rather than auto-merged so you stay in control.
Can Lead Sorted handle a CSV without proper headers?
Yes. The AI extracts fields by reading the row content rather than relying on column names. CSVs with missing, misnamed, or merged columns work the same way as well-formatted ones.
What if a lead is missing an email or phone number?
Lead Sorted flags rows with no contact method so you can decide whether to add data manually or skip them. Rows with at least one contact method (phone, email, or social handle) are imported automatically.
Will my lead data be used to train AI models?
No. Lead Sorted uses OpenAI under their zero-retention API agreement — OpenAI does not train on data sent through that endpoint. Your customer data stays yours.
How is this different from cleaning a CSV manually in Excel or Google Sheets?
Manual cleanup means writing formulas to normalise phone numbers, hand-checking duplicates, and trying to extract data from messy free-text columns. Lead Sorted does it in one pass with AI, then keeps the cleaned leads inside a follow-up workspace if you don't want to bounce them to another CRM.
Is there a free trial?
Yes. Every paid plan includes a 14-day free trial with no credit card required up front. The public demo is also free — you can clean one CSV without an account.
