Multi-Line to Single Line
Join multiple lines of text into a single line. Choose your separator: space, comma, pipe, semicolon, or custom. Optionally trim whitespace and skip blank lines.
About Multi-Line to Single Line
This tool joins multiple lines of text into a single line with a separator of your choice. It is useful for converting CSV-style data, building command-line arguments, processing log output, or preparing data for spreadsheets. The trim option removes leading and trailing whitespace from each line before joining. The skip blank lines option removes empty lines that would otherwise produce consecutive separators.
