Examples

1. Database Migration

Data Analyst

Background: An analyst needs to import a large product catalog from an Excel file into a PostgreSQL database.
Problem: The database requires a standard CSV format with specific delimiters and no extra whitespace.
How to Use: Upload the product list, set the delimiter to a comma, and ensure 'Trim Whitespace' is checked.
Example Config: delimiter: ',', trimValues: true, hasHeader: true
Outcome: A clean CSV file ready for immediate ingestion into the database.

2. Email List Preparation

Marketing Coordinator

Background: A marketing team maintains a subscriber list in Excel but needs to upload it to a web-based mailing service.
Problem: The mailing service only accepts CSV files and fails if there are inconsistent spaces in the email addresses.
How to Use: Upload the subscriber spreadsheet and enable the 'Trim Whitespace' feature to ensure all email addresses are correctly formatted.
Example Config: trimValues: true, hasHeader: true
Outcome: A perfectly formatted CSV file that imports without errors into the mailing service.
