Text Columns Merger

Merge two text columns side by side with a custom separator.

How to Use

What Is Text Columns Merger?

The Text Columns Merger combines two columns of text line by line with a configurable separator. Enter text in Column A and Column B, choose a separator (tab, comma, space, pipe, or custom), and the tool merges them so each line from A is joined with the corresponding line from B. If the columns have different numbers of lines, shorter column lines are filled with empty strings. This is useful for combining lists, creating CSV data, or merging parallel text content.

Why Use Our Text Columns Merger?

  • Merge two lists or columns of text line by line
  • Configurable separator for different output formats
  • Handles unequal column lengths gracefully
  • Create delimited data from separate columns

Common Use Cases

Data Combination

Merge separate lists (names + emails, IDs + values) into combined rows.

CSV Creation

Combine columns into comma or tab-separated data.

Content Formatting

Merge parallel text content side by side.

Translation

Combine source and translated text line by line.

Technical Guide

The merger splits both input columns into line arrays. It determines the maximum length and iterates through both arrays, joining each pair of lines with the selected separator. If one column has fewer lines, missing lines are treated as empty strings. The separator options include tab (\t), comma, space, pipe, and a custom text input. The merged result is joined with newline characters. Custom separators allow any text string, enabling complex formatting like wrapping or bracketing.

Tips & Best Practices

  • 1
    Use tab separator for spreadsheet-compatible output
  • 2
    Comma separator creates CSV-like data
  • 3
    If columns differ in length, shorter side gets empty values
  • 4
    Custom separator can be any text including multiple characters
