Vertical Text Generator

Arrange up to 5,000 Unicode grapheme clusters into bounded vertical columns with explicit left-to-right or right-to-left column order.

Privacy: your files never leave your device. All processing happens locally in your browser.

How to use

  1. 1.Enter the text to arrange and choose a column height from 1 to 100.
  2. 2.Select whether logical columns display from left to right or right to left.
  3. 3.Generate the layout, inspect grapheme and column counts, then download the UTF-8 TXT result.

About Vertical Text Generator

Vertical Text Generator rearranges plain-text grapheme clusters into top-to-bottom columns. Enter text, choose a column height from one through 100, and select left-to-right or right-to-left column order. The tool reports source grapheme count and output column count, shows the exact monospaced result, and downloads UTF-8 text without uploading anything to Lizely.

Segmentation uses the browser's Intl.Segmenter at Unicode grapheme granularity through the site's tested fallback. This keeps common emoji sequences, combining accents, skin-tone modifiers, flags, variation selectors, and CRLF behavior together instead of reversing or splitting raw UTF-16 code units. A visible glyph can still render differently across fonts and systems.

The first source graphemes fill the first logical column from top to bottom until the chosen height is reached. Remaining graphemes fill subsequent columns. Left-to-right displays that first column at the visual left. Right-to-left reverses the column display so the first source column appears on the visual right, matching a common traditional vertical reading direction.

Rows use two ordinary spaces between columns. Missing cells in a shorter final column are represented by a full-width blank only when required to keep later columns aligned. Missing cells at the visual right edge are omitted so output lines do not gain unnecessary trailing padding.

Existing CRLF, standalone CR, and LF boundaries each become one full-width blank cell before grapheme layout. They do not start a new independent vertical block. This explicit rule preserves a visible gap in the sequence while keeping one predictable rectangular layout. Consecutive line endings create consecutive blank cells.

The output is plain text, not CSS writing-mode markup, an image, or a document layout. Alignment relies on the destination font treating the chosen characters and full-width blank consistently. Proportional fonts, fallback emoji fonts, tabs, and mixed-width scripts can make columns look uneven even though the plain-text cell sequence is correct.

Input is limited to 5,000 grapheme clusters, output to 50 columns, and height to 100. If a short height would create more than 50 columns, the tool asks for a taller column rather than generating an extremely wide preview. These limits bound segmentation, rendering, horizontal scrolling, and downloaded output.

Malformed UTF-16 surrogate sequences are rejected before segmentation. The tool never silently truncates source text. Empty input, decimal or out-of-range heights, invalid directions, excessive grapheme counts, and excessive column counts produce explicit errors without a partial result.

Use the tool for decorative captions, poetry experiments, vertical labels, short bilingual displays, classroom examples, social posts, or plain-text mockups. It is not a typesetting engine for Japanese tate-chu-yoko, rotated punctuation, ruby annotations, Chinese line breaking, Mongolian layout, bidirectional shaping, or print publishing.

For a real website, CSS writing-mode and appropriate language typography usually provide more accessible vertical layout because text remains responsive and selectable without inserted spaces. For print or graphics, a design application can control glyph rotation, metrics, and page geometry more reliably. This tool is for portable plain-text arrangements.

The downloaded file exactly matches the preview string and uses LF row separators. The Blob URL exists only for the download click and is revoked immediately. Changing text, height, or direction clears the prior result so an old layout cannot be confused with current settings.

No language mapping, dictionary, font service, remote model, or external content database is used. Given the same browser segmentation behavior, source, height, and direction, the generated cell order is deterministic. Always preview the result in the final destination font before publishing.

Methodology & sources

Reject empty or malformed-Unicode input, normalize CRLF before CR or LF into one full-width blank cell per boundary, segment through the site's Intl.Segmenter-based grapheme utility, reject more than 5,000 clusters, validate a whole-number height from one through 100, slice sequential clusters into columns and reject more than 50, reverse only column display order for right-to-left mode, render rows with two-space separators and full-width blanks for internal missing cells while omitting trailing missing cells, join rows with LF, and create a short-lived UTF-8 Blob URL on download click.

Frequently asked questions

Will emoji be split into separate pieces?
The tool uses grapheme segmentation and a tested fallback to keep common joined emoji sequences together.
What happens to existing line breaks?
Each recognized line break becomes one full-width blank cell in the vertical sequence.
Is this the same as CSS writing-mode?
No. It generates portable plain text with spaces, not semantic browser layout.
Is my text uploaded?
No. Segmentation, layout, previewing, and download creation happen locally.
