Sort Letters Inside Words
Sort Unicode letters and numbers inside every word independently without moving punctuation or the words themselves.
Ready. Your working data stays in this browser.
How it works
Each Unicode word is segmented into grapheme clusters, sorted with locale-aware numeric comparison and written back without detaching combining marks.
Practical example
Ascending mode transforms cab bad into abc abd while the separating space remains exactly where it was.
Validation
The calculation is deterministic and explains validation errors instead of silently changing invalid input.
Privacy boundary
Input and output remain in this tab. Copy and download happen through browser APIs without a server upload.
Result passport
Every run reports its tool mode, timestamp and input/output size so transformed data can be audited.
