Spreadsheet export workflow
Extract email addresses from a CSV file
Scan a CSV export for email-shaped values even when the addresses appear across multiple columns. Supported CSV files are parsed locally in your browser.
The File tab is ready for a CSV file. The original rows are not uploaded by the local parser.

Supports: .txt, .csv, .docx, .pdf (Max 10MB each)
Input and output
What to provide
- CSV files containing headers, quoted cells or mixed contact fields.
- Use a file you own or have permission to process; the uploader displays the active size limit.
What you receive
- A flat, normalized list rather than a rewritten spreadsheet.
- Duplicates can be removed and results exported to a new CSV after review.
Worked example
Example input

How to use this workflow

- 2Select filters if the export contains noisy values.
- 3Run extraction and compare the result count with the source.
- 4Review and export the cleaned list.
Accuracy boundaries
- The tool extracts matches; it does not preserve original row-to-address relationships.
- Malformed encodings or delimiters can reduce coverage.
- It cannot determine whether an address is current or consented.
Privacy for this mode
CSV parsing runs in the browser. Anonymous product events use coarse buckets and never include the filename, cell contents, domains or extracted addresses.

Characters look wrong
Re-export the source as UTF-8 CSV and try again.
Expected columns are missing
The output is intentionally a flat address list; retain the source file if row context matters.
Responsible use
Treat exported contact data according to the permissions and retention rules that apply to the source dataset.
Review applicable privacy, anti-spam and data-protection requirements before contacting anyone.
Frequently asked questions
Is the CSV uploaded?
Supported CSV extraction runs locally in your browser.
Does it keep the other columns?
No. It produces a reviewable list of email-shaped matches, not a transformed copy of the source table.
Can it remove duplicates?
Yes. Duplicate removal is enabled by default and can be changed in advanced settings.
