Frequently Asked Questions

How do I convert an Excel column to a comma-separated list?

Simply copy your Excel column (select the cells and press Ctrl+C), then paste into the input area of this tool. The tool will automatically convert each cell into a separate line, then join them with your chosen delimiter.

Tip: For best results, ensure your Excel data doesn't contain extra spaces or line breaks within cells.

What's the best way to format data for SQL queries?

For SQL IN clauses, use the comma delimiter with single quotes around each item. For example: 'item1', 'item2', 'item3'.

For PostgreSQL, you might need to escape single quotes within your data by doubling them ('').

Can I use this tool for JSON array formatting?

Yes! Use the comma delimiter with double quotes around each item. Then simply wrap the output in square brackets to create a valid JSON array: ["item1", "item2", "item3"].

For complex JSON structures with nested objects, you'll need additional formatting beyond this tool's scope.

How does the "Ignore Empty Lines" option work?

When enabled, this option filters out any blank lines from your input before conversion. This is useful when pasting data that might have empty rows or trailing line breaks.

Lines containing only spaces or tabs are also considered empty when this option is selected.
