关于空白规范化
Whitespace cleaning helps when pasted text carries extra spaces, tabs, or stray leading/trailing blanks. Newlines are preserved; consecutive ASCII spaces are collapsed to one so line structure stays intact.
By default, trim ends, collapse spaces, and tabs→spaces are on. Enable “trim lines” to also strip spaces/tabs at the start and end of every line.
Everything runs locally in your browser — nothing is uploaded.
使用方法
- Paste or type your text
- Toggle trim, collapse, or tabs→spaces as needed
- Copy the cleaned result
常见问题
Are newlines removed too?
No. Space collapsing only targets ASCII spaces; newlines are preserved.
How many spaces does a tab become?
Each tab becomes a single space. If collapse spaces is on, consecutive spaces are then squeezed to one.
Is my text sent anywhere?
No. Processing runs entirely in your browser; nothing is sent to toco.tools servers.
