Examples
1. Creating a SQL Query List
Database Administrator- Background
- I have a list of 50 user IDs in a text file that I need to use in a 'WHERE id IN (...)' SQL query.
- Problem
- Manually adding commas and quotes to 50 IDs is tedious and prone to syntax errors.
- How to Use
- Paste the IDs into the input, set the separator to ', ', and ensure 'Remove Empty Lines' is checked.
- Example Config
-
separator: ', ', trimWhitespace: true, removeEmpty: true - Outcome
- A perfectly formatted string of IDs ready to be pasted directly into a SQL statement.
2. Formatting Email Addresses
Marketing Coordinator- Background
- I received a list of email addresses copied from a spreadsheet, but they are scattered across multiple lines with extra spaces.
- Problem
- I need a single, clean string of addresses separated by semicolons for my email client.
- How to Use
- Paste the emails, set the separator to ';', and enable 'Trim Whitespace' to clean up the formatting.
- Example Config
-
separator: ';', trimWhitespace: true, removeEmpty: true - Outcome
- A clean, semicolon-separated string of email addresses ready for bulk mailing.
