Reverse text
Characters respect an emoji as one unit. Words reverse order and keep the spaces. Lines reverse the order of lines.
The result shows up here.
How it works
Reversing the characters of “ação” produces “oãça”, a mirror, not a shuffle. Use it to see whether a field splits an emoji or mishandles direction.
Reversing lines is the practical mode: a log pasted bottom-up, or a list you want flipped. Reversing words changes order, not spelling.
Questions
Can an accent stick to the wrong letter?
The reversal walks code points of the composed string. A stray combining mark would travel on its own.
Do leading spaces vanish?
In word mode they are tokens and stay, on the other side.
Can it read a spreadsheet file?
Only if you paste the text. There is no file upload.
