Merge Lines

What Is Merge Lines?

Merge Lines is a free online text formatting tool that combines separate lines of text into a single line. Instead of manually copying each line and removing line breaks, you can paste your text into the tool and merge it automatically using a separator of your choice.

The tool is useful when working with lists, copied text, data, search terms, keywords, names, product information and other content that needs to be converted from a multi-line format into one continuous line. You can also trim unnecessary whitespace and ignore blank lines before creating the result.

Why Use Merge Lines?

Manually joining lines can be slow and can introduce unwanted spaces or punctuation. Merge Lines provides a quick way to combine text consistently while giving you control over how the resulting line is formatted.

How to Use Merge Lines

Merge your text in a few simple steps by entering your lines and selecting the formatting options you need.

1. Enter your text — Paste or type your content into the input box with one item or sentence on each line.
2. Choose a separator — Select how the individual lines should be separated in the final result, or enter your own custom separator.
3. Select formatting options — Choose whether to trim whitespace from each line and whether blank lines should be ignored.
4. Merge and copy — Click Merge Lines to create the result, then copy it or download it as a text file.

When text is copied from documents, spreadsheets, websites or other applications, it is often divided across multiple lines. This can be inconvenient when a destination requires the information to appear on one line. Merge Lines provides a simple way to join those lines together while retaining the original order of the content.

For example, a list containing “Apple”, “Banana” and “Orange” can be converted into “Apple, Banana, Orange” with a comma and space separator. The same input can also be turned into “Apple Banana Orange”, “Apple | Banana | Orange” or another format by selecting a different separator.

When Should You Merge Lines?

Merging lines is useful when preparing lists for forms, search fields, spreadsheets, databases, scripts and other applications that expect data on one line. It can also help clean up text copied from PDFs, documents and web pages where unwanted line breaks have been introduced.

What Happens to Spaces and Blank Lines?

By default, Merge Lines trims whitespace from the beginning and end of each line and ignores blank lines. These settings help produce a clean result. If preserving whitespace or empty lines is important, either option can be disabled before merging.

Merge Lines: Options and Limitations

Merge Lines combines lines in their original order. It does not sort, rewrite, translate or otherwise interpret the content. The separator is inserted between the resulting lines, allowing you to control the exact basic structure of the merged output.

The tool works with ordinary text entered or pasted into the browser and does not require a file upload. Very large amounts of text may be limited by the memory and performance of the browser or device being used. If you disable whitespace trimming, spaces and tabs at the beginning or end of each line are retained.
