Normalize Whitespace

text.normalize_whitespace

ProductionBounded custom (Class B)Deterministicstrictfastv1.0.0

File inputNo network

Overview

Normalizes whitespace deterministically: converts CRLF/CR to LF, strips trailing spaces, collapses repeated spaces/tabs, and applies a preservation policy (compact, preserve_lines, preserve_paragraphs, markdown_safe). Fenced code blocks are preserved by default and Markdown hard line breaks are kept in markdown_safe mode. Accepts file input via file_ref — no need to extract file content first.

Whitespace noise breaks comparison and dedup — we clean it deterministically so your pipelines get consistent text.

Reliability

STRICT and deterministic — identical text and options always yield identical output. Fenced code blocks are preserved verbatim when preserveCodeBlocks is true (default). Input validation (not retryable): unsupported mode; text and file_ref both missing.

Context footprint

Returns the normalized text and a small change summary. A successful call costs 1 execution credit.

When to use it

When you compare, hash, or deduplicate text and want predictable whitespace.

Do not use on whitespace-significant formats (some code, fixed-width tables) where every space carries meaning.

Scope

Note

We normalize whitespace in your text — line endings, repeated spaces, trailing spaces — while preserving the line and paragraph structure you choose.

How we handle your data

Sensitive output possible

What this means

This skill may receive sensitive content and may return submitted, transformed, extracted, or reformatted content.

Squillify guarantees

Runs inside Squillify
This skill runs inside Squillify.
Payloads are not sent to an external service by this skill.
Squillify does not permanently store submitted payloads.
Telemetry records metadata only, not submitted content.
Submitted payloads are not used for training.
Submitted payloads are not reviewed by humans.
This skill does not target sensitive data.
The response may contain submitted or transformed content.

Your responsibility

Squillify does not determine whether submitted content is sensitive. Your application is responsible for deciding what data it is allowed to submit. Your application is responsible for securing the response.

Input schema

Field	Type	Required	Description
text	string	No	Bounded inline text source. Required unless file_ref is provided.
file_ref	string	No	Tenant-scoped opaque text-file reference. Omit it to use the required inline text; never send both.
mode	string	No	Preservation mode; omit it for preserve_paragraphs.
trim	boolean	No	Whether outer whitespace is trimmed; omit it for true.
normalizeNewlines	boolean	No	Whether CRLF and CR become LF; omit it for true.
collapseSpaces	boolean	No	Whether repeated spaces and tabs collapse; omit it for true.
preserveCodeBlocks	boolean	No	Whether fenced code blocks are preserved; omit it for true.

Output schema

Field	Type	Required	Description
ok	boolean	Yes	Always true for a successful normalization.
text	string	Yes	Normalized bounded text.
changes	object	Yes	Closed change-summary object with originalLength, normalizedLength, and newlineCountChanged properties.
