What is a text letter swapper?
learn more about this toolWith this online tool, you can swap pairs of letters in words in any text. For example, if you have the text with three words "elephants are running", then after swapping pairs of letters in all words, you will get a cryptogram "lepeahtns rae urnnnig". By default, the word is split into groups of two letters, and the letters in each group change their order to the reverse. The "Group Size" option lets you change how many letters to group together before swapping them around. For example, if you set the group size to 3, then packs of every three adjacent letters will be reversed in every word. For example, the word "flower" will become "olfrew". If you group the letters in the word "flower" into packs of 4 characters, you'll get one complete group "flow" and a second incomplete group "er". In this case, you can turn on the "Swap Incomplete Groups" option to have letters in the partial group "er" swapped as well, and the result will be "wolfre". If you turn off this option, then incomplete groups will be left unchanged, and the result will be "wolfer". The next option is "Preserve Case" and if you enable it, then the after swapping the letters, they will maintain their case based on their original position. For example, if you have a sentence that begins with a capital letter (such as "Cows are white"), then this option will ensure that the first letter of the sentence remains capitalized even after the letter exchange operation (the output will be "Ocsw rea hwtie"). If this option is disabled, then each letter will move its case with it (the output will be "oCsw rea hwtie"). The last two options allow you to set the rules for swapping letters in words with apostrophes and hyphens. There are three ways to swap letters in such cases. The first option is called "Stop at Hyphens" (and "Stop at Apostrophes" for apostrophes) and it considers all parts of a word separated by a hyphen (or apostrophe) as individual words. For example, in this case, the word "ice-cream" will become "cie-rcaem" (when the group size is 2). The second mode is called "Swap Hyphens" (and "Swap Apostrophes" for apostrophes) and it treats hyphens and apostrophes as letters and moves them along with all other letters. In this example, the word "ice-cream" will become "ci-ercaem". The third mode is called "Skip Hyphens" (and "Skip Apostrophes" for apostrophes). It ignores the hyphen and apostrophe symbols and rearranges letters from separated word parts as if there were no hyphens or apostrophes. In this case, the word "ice-cream" turns into the word "cic-eerma" (hyphen stays fixed). Textabulous!

Click to useSwap Letters in Pairs
In this example, we exchange every two consecutive letters of every word. To do this, we specify the group size equal to 2 in the options, and we also activate the option "Preserve Case" so that the first letter of the sentence remains uppercase even after letters have been exchanged.

Swap Triplets of Letters
In this example, we split the words in Theodore Roosevelt's quote into sets of three characters and reverse their order. If the last set contains less than three characters, then we also swap letters in it. Additionally, we select the "Stop at Apostrophes" mode so that the letters in both parts of the word "you're" are swapped separately.

Rearrange Letters in Words with Hyphens
This example rearranges letters only in full batches of 7 symbols (batches with less than 7 symbols are not rearranged). As the input data set is a list of spelled numbers that include a hyphen (such as "twenty-one"), the option "Swap Hyphens" is turned on. As a result, in the output, each word begins with a hyphen but everything after a hyphen is not reversed as none of the spelled digits have seven letters.
