About Text Line Processor
Welcome to the Text Line Processor, a powerful text manipulation tool that helps you transform, format, and process text on a line-by-line basis. Whether you need to add line numbers, sort lines, remove duplicates, transform case, filter content, or apply custom templates, this tool provides 20+ operations to handle all your text processing needs with ease.
At a Glance
Text Line Processor applies one operation to every line of pasted text. Operations include numbering, prefixes and suffixes, templates, sorting, filtering and find and replace, with a processing summary.
| Feature | What you get | Good for |
|---|---|---|
| Line numbering | Add numbers with a starting number, zero-padding (01, 001) and a separator such as a period, parenthesis or colon. | Numbering a list of items or steps |
| Templates | Use {{line}} for the line text and {{linenumber}} for its number. The template [{{linenumber}}] {{line}} turns Hello into [1] Hello. | Custom formats for every line in a list |
| Prefix, suffix and wrap | Add text before or after each line, or wrap lines in tags such as <li> and </li>. | Adding bullets or building HTML list items |
| Sorting | Sort A-Z or Z-A, by length (short to long or long to short), or numerically by the leading number. | Ordering word lists, names and numbered entries |
| Duplicates and case | Remove duplicate lines with case-sensitive or case-insensitive matching, or convert to uppercase, lowercase or title case. | Cleaning lists with repeated or inconsistent entries |
| Filter and replace | Keep or remove lines that contain given text or match a regular expression, or find and replace text across all lines. | Extracting lines such as errors from a log |
| Line cleanup | Reverse line order or the characters within lines, trim whitespace, remove empty lines, or skip blank lines. | Tidying pasted lists before reuse |

Frequently Asked Questions
How do I add line numbers to my text?
Select "Add Line Numbers" from the operation dropdown, then configure the starting number, number padding (for leading zeros), and separator. Click "Process Text" to add line numbers to each line. You can also use "Apply Template" with {{linenumber}}. {{line}} for more customization.
How do I remove duplicate lines from my text?
Select "Remove Duplicates" to remove exact duplicate lines, or "Remove Duplicates (Case-Insensitive)" to treat lines with different capitalization as duplicates. The tool preserves the first occurrence of each unique line and shows how many duplicates were removed.
What placeholders can I use in templates?
The Text Line Processor supports two placeholders: {{line}} which is replaced with the actual line content, and {{linenumber}} which is replaced with the current line number. For example, the template "[{{linenumber}}] {{line}}" would produce "[1] First line", "[2] Second line", etc.
How do I filter lines containing specific text?
Select "Filter Lines Containing..." from the operation dropdown, then enter the text you want to search for in the filter field. Only lines containing that text will be kept. Use "Filter Lines NOT Containing..." for the opposite effect. Toggle case sensitivity as needed.
Can I sort lines by different criteria?
Yes! The tool offers multiple sorting options: alphabetical ascending (A-Z), alphabetical descending (Z-A), by length (shortest or longest first), and numerical sorting (based on leading numbers in each line). All sorting maintains the complete line content.
How do I wrap each line with HTML tags?
Select "Wrap Lines" from the operation dropdown, then enter the opening tag (like <li>) in the "Before" field and the closing tag (like </li>) in the "After" field. Each line will be wrapped with these tags, perfect for creating HTML lists or other markup.
