🔢Line Numbers, Prefix & Suffix Documentation & Guide
Text & Content
The Line Numbers, Prefix & Suffix tool allows developers, writers, and data specialists to batch-prepend and append custom characters, delimiters, or sequential numerals to every line of text.
📋How to Use This Tool
- Paste Text Lines: Enter or paste multi-line content into the input text area.
- Configure Prefix & Suffix: Specify any characters to attach at the beginning (e.g. "> " or quote) or end (e.g. comma or semicolon) of each line.
- Select Numbering Format: Choose from sequential dots (1.), parentheses (1)), padded digits (01., 001.), or bracketed counters ([1]).
- Click Add Prefix/Suffix: Process all lines instantly and copy the formatted dataset to your clipboard.
⚙️Technical & Algorithmic Details
• Delimiter Precision: Appends leading and trailing strings without altering intra-line spacing unless Trim Whitespace is activated.
• Padding Math: Zero-padding utilizes native String.prototype.padStart for consistent tabular alignment across variable-length documents.
• Selective Empty Line Handling: Optionally bypasses empty or whitespace-only lines to maintain paragraph breaks.
💡Practical Use Cases & Best Practices
- Wrapping arbitrary lists of IDs into SQL "IN ('id1', 'id2')" clauses.
- Formatting brainstorming notes into Markdown unordered or ordered bullet lists.
- Adding sequential logging indices or timestamp prefixes to debugging traces.
