Quickly clean up text by removing unwanted line breaks, stripping empty lines, trimming whitespace, and normalizing formatting. Multiple text cleanup operations available: remove all line breaks (join to single line), remove empty lines only, remove duplicate lines, add line breaks at specific intervals, trim each line, and convert multiple spaces to single spaces. Preview results in real-time as you type.
Paste your text into the input textarea. Choose a cleanup operation from the buttons: 'Remove All (space)' joins all lines with a space between them, 'Remove All (join)' removes line breaks completely, 'Remove Empty Lines' keeps content lines but removes blank lines, 'Remove Duplicates' eliminates repeated lines, 'Add Breaks Every N' inserts line breaks at regular intervals, 'Single-Space' normalizes multiple spaces to one, or 'Trim Lines' removes leading/trailing whitespace from each line. The result appears instantly in the output area. Use the Swap button to move the output back to input for chaining operations.
Line break removal is essential for: cleaning up text copied from PDFs where every line has forced breaks, preparing text for use in single-line fields (emails, forms, databases), reformatting poetry or quotes copied from web pages, removing extra blank lines from code or data files, cleaning up text exported from legacy systems with fixed-width formatting, preparing content for CSV import by removing internal line breaks, normalizing text formatting before processing with other tools, and converting multi-line addresses or data into single-line format.
The tool uses JavaScript string manipulation methods: String.replace() with regular expressions for pattern-based replacements, String.split('\n') for line-based operations, Array.filter() for removing empty lines, and Set for deduplication. Line break detection handles both Unix (\n) and Windows (\r\n) line endings. The 'Add Breaks' feature uses a regex that matches every N characters and inserts a newline, respecting word boundaries when possible. Character and line counts are updated in real-time using efficient string length and split operations.
Paste your text into the input, then click 'Remove All (space)' to replace every line break with a space (preserving word separation), or 'Remove All (join)' to remove line breaks completely (joining words without spaces). The cleaned text appears in the output area.
Yes. Click 'Remove Empty Lines' to keep all lines that contain text while removing blank lines (lines that are empty or contain only whitespace). This is useful for cleaning up code or data files with excessive blank spacing.
Yes. Use the Swap button to move the output back to the input field, then apply another operation. For example, first remove empty lines, swap, then trim each line for a thorough cleanup.
