Merge Lines

What is “Merge lines” and why use it?

The “Merge lines” tool allows you to take text that spans multiple lines and combine it into one continuous line or block using your chosen separator. This is especially helpful when you have lists, free-form text, or data you’d like to compress into a single line.

When to use the tool

Data preparation & CSV formatting

If you're exporting data, cleaning spreadsheets, or preparing CSV fields that must be one-liner, the Merge lines tool saves time by converting multiline text into a single field.

Content editing & social sharing

For social media captions, metadata fields or any place where line breaks aren’t allowed or desired, you can merge multiple lines into one clean block.

How to use the tool

1. Paste or type your text into the left textarea.
   Example:
   Line 1
Line 2
Line 3
2. Choose your separator (e.g., “, ”, “ | ”, “; “) using the “Separator” field.
3. Check or un-check “Trim spaces and empty lines” to remove unwanted blank lines and extra spaces.
4. View the merged result in the output box. Copy or download via the buttons.

Best practices & tips

• If you want to use a comma separator but your text contains commas, choose a different character such as “|” to avoid confusion.
• Use “Trim spaces” option when your input text may contain accidental blank lines or trailing spaces.
• When merging for CSV or spreadsheet import, make sure the resulting line doesn’t exceed your field length limits.

Related tools you may find useful

• Trim whitespace – remove leading or trailing spaces on each line.
• Remove duplicate lines – eliminate repeating lines before you merge.
• Split text into paragraphs / Join into one block – similar workflow for paragraphs instead of line-by-line merging.

Frequently Asked Questions (FAQs)

Will the tool remove blank lines by default?

Only if “Trim spaces and empty lines” is checked. If unchecked, blank lines will result in extra separators.

Can I upload a file or drag-and-drop?

At present the tool works via textarea only. File upload support may be added later.

What happens to the separator if my input lines already end with that separator?

The tool will still insert your chosen separator between each line. If your lines already include separators you may need to clean them or select a different separator to avoid duplication.
