Text Line Operations

Text line operations tool helps batch-process multi-line text with sorting, deduplication, filtering, numbering, and formatting, suitable for logs, lists, configs, and script preprocessing.

Core Features

• Supports ascending, descending, length-based, and random sorting.
• Supports normal dedupe, case-insensitive dedupe, and trimmed dedupe.
• Supports contains, excludes, prefix/suffix match, and regex filtering.
• Supports batch prefix/suffix, line numbering, blank removal, and line joining.

Use Cases

• Log cleaning and duplicate line removal.
• Preprocessing user lists, keywords, and block/allow lists.
• Batch normalization of line-based configuration entries.
• Fast transformation of script argument lists.

Common Operation Notes

• Remove Empty Lines deletes only lines with no characters at all.
• Remove Blank Lines deletes both empty lines and lines containing only spaces or tabs.
• Remove Duplicates compares lines by original text and is case-sensitive by default.
• Deduplicate Ignore Case treats A and a as the same value.
• Deduplicate Trimmed removes leading and trailing spaces before comparing lines.
• Keep Unique Only keeps lines that appear exactly once and removes all repeated lines.

Tips

• Keep original text on the left and apply different operations as needed.
• Validate regex filters with a small sample before full processing.
• Use copy and download to continue processing in other tools.
