Text Line Operations

Overview

Text Line Operations is a batch processor for multi-line text. It supports sorting, deduplication, filtering, numbering, prefix/suffix editing, and line joining for list/log workflows.

Core Features

• Sorting: ascending, descending, by length, random.
• Deduplication: normal, ignore-case, trimmed, keep-unique-only.
• Filtering: contains, excludes, starts-with, ends-with, regex.
• Other actions: remove empty/blank lines, reverse, add/remove line numbers, add prefix/suffix, join lines.

Use Cases

• Log cleanup and duplicate removal.
• User list, keyword list, and allow/block list preprocessing.
• Batch normalization of line-based configuration data.
• Fast transformation of script argument lists.

Common Operation Notes

• Remove Empty Lines deletes only truly empty lines.
• Remove Blank Lines also removes lines containing only spaces/tabs.
• Ignore-case dedupe treats A and a as the same.
• Trimmed dedupe compares lines after trimming edge spaces.
• Keep Unique Only keeps lines that appear exactly once.

Tips

• Keep source text unchanged and apply operations iteratively.
• Validate regex filters on a small sample first.
• Use copy/download to continue processing in downstream tools.
