Text / Formatter

Text / Formatter

Transform text: case, trim, pad, replace, split, slugify, extract and count.

What it does

One node with an operation selector, rather than a dozen tiny nodes. It converts case (Uppercase, Lowercase, Title Case, camelCase, snake_case, kebab-case), trims, pads, replaces (plain or regex), splits and joins, slugifies, truncates with an ellipsis, and substitutes a default value when the text is empty. It also extracts every email, URL, number or phone number found in the text, and counts words or characters. The selector both drives the transformation and decides which extra settings the UI shows.

A single transformed value comes back in result. The extract operations return matches, always an array, so an empty result is still iterable. The count operations return count. Character counting is by code point, so an accented letter or emoji counts once rather than by its UTF-16 units.

When to use it

Use this node to tidy scraped or user-supplied text before it travels downstream: turning a heading into a slug, pulling every email address out of a page, or normalizing a key into snake_case — without dropping to a Code node.

Inputs and settings

Setting	Notes
Operation	What to do with the text. One of Uppercase, Lowercase, Title Case, camelCase, snake_case, kebab-case, Trim, Pad, Replace, Split, Join, Slugify, Truncate, Default if empty, Extract emails, Extract URLs, Extract numbers, Extract phone numbers, Word count or Character count. Defaults to Uppercase.
Text	The text to transform. Bind an upstream value with {{ }}, for example {{ $json.description }}.
Target Length	For Pad: pad until the text reaches this many characters. Defaults to 0.
Pad With	For Pad: the characters repeated to fill the space. Defaults to a single space.
Pad Side	For Pad: which end to pad, Start or End. Defaults to Start.
Find	For Replace: the text or pattern to look for.
Replace With	For Replace: the text put in place of each match.
Treat Find As Regex	For Replace: read the Find field as a regular expression. Defaults to off.
Regex Flags	For Replace: flags for the pattern, such as gi. Defaults to g.
Separator	For Split and Join: the string to split on, or the string placed between joined items. Defaults to ,. Splitting on an empty separator splits into individual characters.
Maximum Length	For Truncate: keep at most this many characters. Defaults to 20.
Ellipsis	For Truncate: appended when the text is shortened. Defaults to ….
Default Value	For Default if empty: returned when the text is empty or only whitespace.

Outputs

• Case conversions, Trim, Pad, Replace, Split, Join, Slugify, Truncate and Default if empty return the transformed value in result. Split returns an array; Join expects an array as input text and returns a joined string.
• Extract emails, Extract URLs, Extract numbers and Extract phone numbers return every match found in matches, an array that is empty rather than absent when nothing matches.
• Word count and Character count return the count in count. Character counting is by Unicode code point.

Dependencies and credentials

• No credential or node dependency is required. The node runs entirely in the browser.

Example workflow

Place Text / Formatter after a node that scrapes a page, set Operation to Extract emails, and point Text at {{ $json.html }}. Every email address on the page comes back in matches. Chain a second Text / Formatter node with Operation set to Slugify on a page title to produce a URL-safe filename before saving.

Troubleshooting

• Replace with Treat Find As Regex on fails if Find is not a valid regular expression — check the pattern and Regex Flags.
• Split with an empty Separator splits the text into individual characters rather than failing.
• Join expects an array; if the incoming text is not an array, it is treated as a single-item list.
• Extract operations never fail on no matches — they return an empty matches array instead.
