How does it work?

This tool duplicates lines in your text and increments any numbers found in each duplicate. It's useful for creating sequences with increasing numeric values.

The process follows these steps:

• The tool identifies the lines you want to duplicate (all lines by default)
• It creates the specified number of duplicates for each selected line
• For each duplicate, it finds all numbers in the original line and increments them by the duplicate's position
• The original lines remain unchanged, and the duplicates are inserted after each original line

Example

Item 10: First item
Item 20: Second item
Item 30: Third item
Item 40: Fourth item

Item 10: First item
Item 11: First item
Item 12: First item
Item 20: Second item
Item 21: Second item
Item 22: Second item
Item 30: Third item
Item 31: Third item
Item 32: Third item
Item 40: Fourth item
Item 41: Fourth item
Item 42: Fourth item

Parameters

• Input text: The text containing lines and numbers you want to duplicate and increment
• Number of duplicates: How many duplicates to create for each selected line
• Start line: The first line to process (1-based index)
• End line: The last line to process (0 means process all lines to the end)

This tool is useful for:

• Creating test data with sequential increasing values
• Generating numbered lists with increasing values
• Preparing data for batch processing with increasing indices
• Creating countup sequences
• Generating code templates with increasing numeric identifiers
