Split text into columns for balanced side-by-side display

The result keeps every line in its original order, preserves intentional blank lines, and returns both each column's line array and a ready-to-display text value. It is useful for programs, lists, scripts, labels, and any other line-oriented material that needs a clean side-by-side presentation. The same deterministic operation can run interactively in the browser or be automated through the API.

Turn one long list into a balanced layout

Paste the complete text and choose how many columns the final display needs. The splitter treats the content as an ordered sequence of lines, then divides that sequence into contiguous groups whose sizes differ by no more than one line. When the division is uneven, the earlier columns receive the extra lines. For example, seven lines divided into three columns produce groups of three, two, and two. This approach makes the result predictable while avoiding the visual imbalance caused by putting every remainder line into the last column. Each returned column includes its one-based position, an array of its individual lines, and a text value joined with newline characters. Use the array when rendering line elements or table cells, and use the text value when inserting a whole column into a plain-text field. The original reading order remains intact from the first column through the last, so no sorting or interpretation is applied to your material.

Understand how lines and empty space are handled

Line boundaries are recognized whether the input uses Unix newlines, Windows line endings, or older carriage-return separators. The output normalizes each column's combined text to newline characters, which gives scripts a stable result across operating systems. Blank lines are meaningful and are preserved as empty strings in the line arrays; they still count toward balancing because removing them could change paragraphs, verse, forms, or carefully spaced production notes. Even an empty text value represents one empty line, matching the way splitting a text field behaves consistently. The requested column count is also honored exactly. If you ask for more columns than there are lines, the additional columns are returned with an empty line array and empty text instead of silently reducing the count. That exactness is helpful when a surrounding layout already has a fixed number of panels. No words are wrapped, measured, hyphenated, or moved between lines: prepare any desired wrapping before calling this capability.

Render, export, or automate the result safely

For a side-by-side interface, iterate over the returned columns in order and place each column in an equal-width container. Within a column, render the lines from its array to retain explicit blank rows, or display its text value in a preformatted element. A print workflow can map the same structure into page columns, labels, cue cards, or a document-generation template. Because the algorithm is deterministic and uses no network, random values, or timestamps, identical input always produces identical output. This makes it suitable for build systems, publishing pipelines, repeatable tests, and cached transformations. Validation is intentionally strict: the text must be a string, and the column count must be an integer of at least one. Invalid values fail instead of being rounded or guessed, preventing a typo such as zero, a fraction, or a numeric string from creating an unexpected layout. Browser use is available for quick work, while an API request costs $0.002 when the same transformation belongs in an automated process.
