Join Text Lines & Strings Online

This is a simple online utility that converts multiple lines of text into a single continuous string.
It removes line breaks and connects each line using a separator of your choice (space, comma, dash, pipe, or any custom character).

If you copied data from Excel, a PDF, a website, logs, or a database and it appears one item per line — this tool turns it into a usable inline format instantly.

(space by default)

How this Tool Works

It’s intentionally simple.

  1. Paste your text into the input box
  2. Enter a separator (optional)
  3. Click Join Lines
  4. Copy the result

That’s it.

What This Tool Does

The tool reads each line as an individual value and joins them together in order while preserving the original text.

Input

apple
banana
mango
orange

Output (comma separator)

apple,banana,mango,orange

You can also use:

  • space → apple banana mango orange
  • comma + space → apple, banana, mango, orange
  • pipe → apple|banana|mango|orange
  • dash → apple-banana-mango-orange

Why You Would Use It

Line breaks are useful for reading, but many platforms, programs, and code environments require data in a single line format.
Manually fixing this is slow and error-prone — especially when you have dozens or hundreds of entries.

This tool quickly converts vertical lists into horizontal text.

Key Features

  • Removes line breaks instantly
  • Supports custom separators
  • Handles large text lists
  • Preserves original text order
  • One-click copy to clipboard
  • Works directly in your browser

Separator Guide

The separator is the character placed between each line after merging.

SeparatorWhen to Use
SpaceNormal readable sentences
,CSV values, tags, IDs
,Keywords or human-readable lists
``
-URL slugs or filenames
","JSON or quoted values

Common Use Cases

For Developers

Prepare values for:

  • SQL IN queries
  • API parameters
  • environment variables
  • configuration files
  • JSON or array formatting
  • testing datasets

Instead of editing each line manually, you can format entire datasets in seconds.

For Excel & Spreadsheet Work

Spreadsheet exports usually appear as one value per row. Many systems, however, expect a single-line input.

Typical tasks:

  • product SKU uploads
  • importing IDs
  • CRM bulk actions
  • CMS category/tag fields

Paste a column → join → copy the result.

For SEO & Marketing

Marketers often work with keyword lists or tags.

Use the tool to prepare:

  • keyword sets
  • tag fields
  • ad groups
  • metadata entries
  • email recipient lists

It converts messy copied lists into clean, ready-to-paste text.
