About this calculator

This tool merges every line of a block of text into a single line, replacing the line breaks with a separator you choose — a space, comma, or any custom character. It's the reverse of splitting text into lines, and it processes pasted content instantly without needing a spreadsheet or text editor macro.

Developers turning a column of values into a comma-separated array for code, writers collapsing a list into a single sentence, and anyone cleaning up text copied from a PDF (which often breaks mid-sentence at the end of every line) use this to reformat text in one step instead of manually deleting dozens of line breaks.
