The recurring problem
Why make this a workflow?
Exported data often contains whitespace, duplicates, mixed case, blank rows, tracking parameters, or malformed values. One-off spreadsheet cleanup is difficult to reproduce and review.
Operations & migration
Turn messy exported lists into a validated import file
Replace fragile copy-paste sequences with a repeatable pipeline: import locally, select values, normalize, validate, deduplicate, compare, and export in the target format.

Recommended steps
- 1
Import locally
Read TXT, CSV, or JSON in the browser and inspect the row count before processing.
- 2
Select and normalize
Extract the required field, trim whitespace, normalize case, and remove empty values.
- 3
Validate
Filter values using deterministic patterns appropriate to emails, URLs, IDs, or allowed codes.
- 4
Deduplicate and compare
Keep stable first occurrences and compare against a suppression, existing, or reference list.
- 5
Export safely
Download a reviewed TXT, CSV, or JSON result without uploading the source dataset.
Concrete example
Input sketch
[email protected] [email protected] invalid@localhost [email protected]
Reviewed output
[email protected] [email protected] 2 unique valid-looking addresses
Visible steps
See which operation changed the count rather than hiding logic in a formula chain.
Recipe without records
Share the cleanup method while excluding contact or customer data.
Repeatable migration prep
Apply the same verified sequence to the next export.
Limits to review before production
- Format checks do not prove an email inbox exists or that contacting it is lawful.
- CSV encoding and multiline fields require careful preview before import.
- Keep source backups and sample-check high-impact migrations.
Useful free tools
CSV Column Extractor
Extract one column from CSV, TSV, semicolon, or pipe-delimited data online. Select by header name or column number with quoted-field support.
Email Extractor
Extract email addresses from text, documents, logs, HTML, or copied data. Validate, lowercase, deduplicate, and export a clean email list locally.
Remove Duplicate Lines
Remove duplicate lines from a list while preserving the original order. Ignore case, trim whitespace, and clean empty lines instantly in your browser.
Compare Lists
Compare two lists online to find common items, items only in list A, and items only in list B. Case-sensitive and case-insensitive comparison supported.
Questions about this workflow
Can I import a CSV file?
Yes. Studio reads supported files locally and can extract or process values without an upload.
Does deduplication merge customer records?
No. It removes matching list values; entity-resolution and record merging need explicit business rules.
Can a coworker reuse the cleanup method?
Yes. Export or share a Recipe containing only operations and options, then provide the dataset separately through an approved channel.
