Prepare Cleaner Lead Data

Lead List Cleaner

Remove duplicate leads, trim inconsistent fields, normalize email case, and download a cleaner CSV before outreach or CRM import.

Add Your Lead List

Paste a table with a header row or choose a CSV or TSV file from your device.

Supports comma, tab, and semicolon separators. Maximum 10,000 data rows.
Auto Detect prefers Email, then Phone, Company, and Entire Row.

Cleaned List Preview

Review the cleaned rows before copying or downloading the complete file.

Clean the sample list or add your own data to preview the results.

The preview shows up to 50 rows. Copy and Download include every cleaned row. Formula-like cells are protected in downloaded CSV files when that option is selected.

Know What Changes

The cleaner applies transparent formatting and duplicate rules without guessing missing lead information.

Local Processing

Your pasted or uploaded lead list stays in your browser and is not stored by TradeGoAI.

Predictable Cleanup

Leading and trailing spaces are removed, blank rows are dropped, and email case is normalized when selected.

Transparent Deduplication

The selected field determines duplicates. Blank keys remain separate so unrelated leads are not merged.

Frequently Asked Questions

Learn how files, duplicate keys, blank values, and browser-only processing are handled.

What files can I clean?

You can paste data or upload a CSV or TSV file with a header row. The cleaner supports comma, tab, and semicolon separators.

Is my lead list uploaded or saved?

No. Your list is read and cleaned in your browser. The tool does not send the file or its contents to TradeGoAI.

How are duplicate leads identified?

Choose Email, Phone, Company, or Entire Row. Auto Detect uses an email column first, then phone, then company, and finally the complete row.

What happens when the duplicate field is blank?

Rows with a blank duplicate key are kept. The cleaner does not merge unrelated leads simply because the selected field is empty.

Does this tool verify email addresses or companies?

No. It standardizes and deduplicates the data you provide. Use an email verification or lead enrichment tool before outreach.
