Ideal for turning data columns into CSV-ready strings, flattening list inputs for spreadsheet pasting, or transforming editor content for JSON arrays. Great for writers, developers, and data processors.

Useful Tools & Suggestions:

If you’re flattening a column into a comma-separated line, Convert Newlines to Spaces might be handy too especially if you’re switching formats for inline display. And if you’re getting your column from a messy source, Remove Empty Lines helps strip out the junk before the merge. It’s a good combo when you’re prepping content for CSVs, forms, or just trying to tighten things up into a single, readable line.
