About the Single Line to Multiline Text Converter

The Single Line to Multiline Text Converter transforms one long line of text into clean line-by-line output. It is useful when you receive comma-separated, semicolon-separated, or custom-delimited text and need every item on its own line for editing, searching, filtering, or exporting.

⭐ What it does

This tool splits a single line into multiple lines based on the separator you choose. You can split by comma, semicolon, pipe, tab, space, or any custom separator string. After splitting, each item is placed on its own line in the output area.

⚙️ How to use

  1. Paste your single-line text into the Input text field, or upload a .txt or .csv file.
  2. Choose the separator used in your text from the Split by separator dropdown.
  3. If needed, pick Custom... and enter your own separator string.
  4. Enable Trim whitespace per item to remove spaces around each result item.
  5. Enable Skip empty items to remove blank values caused by repeated separators.
  6. Copy the output or download it as TXT or CSV.

🔎 Example

Input (single line):

apple, banana, cherry, date

Separator: Comma

Output (multiline):

apple
banana
cherry
date

⭐ Available separators

  • Comma (,) - good for standard lists and CSV-style values
  • Semicolon (;) - useful for region-specific CSV formats
  • Pipe (|) - common in logs and custom data exports
  • Tab - useful for TSV-like content
  • Space - splits a sentence or spaced list into lines
  • Custom - split by any string such as ::, --, or |

⚙️ Options

  • Trim whitespace per item - removes leading and trailing spaces from each extracted item.
  • Skip empty items - removes empty lines when separators appear back-to-back.

⚠️ Notes

  • All processing happens in your browser. Your text is never uploaded to a server.
  • For the Space separator, multiple spaces and line breaks are handled as one separator.
  • If you select Custom and leave it empty, the tool keeps the full input as one line.
