Guides
Clean up messy spacing in text — collapse repeated spaces or tabs down to a single one, or strip them out completely. Handy for text pasted from a spreadsheet or PDF where columns get padded with runs of spaces, or code with inconsistent tab indentation.
How to use it
- Paste your text into the input box.
- Choose what counts as Considered As Whitespace — Tab, Space, or Any Space or Tab.
- Choose whether to only collapse duplicates, or remove the character entirely.
- Copy or download the result.
Settings
- Considered As Whitespace — which character the tool acts on: Tab, Space (the default), or Any Space or Tab (treats runs of either as one unit).
- Remove Duplicated Whitespaces Only — a run of two or more of the chosen character becomes exactly one (a single character stays untouched).
- Remove All Whitespaces — every occurrence of the chosen character is deleted, even single ones.
Only the character you select is affected — choosing Tab leaves spaces exactly as they are, and vice versa, unless you choose Any Space or Tab.
