In power query, the transformations transpose the text from rows to columns and then merges all the columns together. This same table is the also loaded to Power Query (on the second refresh). This VLOOKUP is combined with other functions to account for spaces, punctuations, and errors.

This table is loaded into Excel.Ĭolumn G, Return, then carries out a VLOOKUP, referencing the Alphabet table, returning the shifted letters. Each character of text is now in a cell going down a column. It then splits the text by character and transposed it from a column to a row. we created this table by loading the Text table from the inputs into power query on refresh. In column E we have a table returned by Power Query.

You can download the Excel model at the end of this post. In this model, you can both encrypt and decrypt a text string using an alphabet shift. So, to modernize the resources out there, I have created a Caeser Cipher using Excel and Excels Power Query in Office 365. However, I wanted to see if I could create a Shift Caesar Cipher in Excel without the use of VBA (before I go on and try some more complicated ones), that could both encrypt and decrypt string text with ease.Ī Google search did turn up some good results, however, these were rather old and did not make use of Excel Power Tool functionalities. However, it has lead to more secure encryptions such as Vigenère cipher and ROT13.Įxcel is no match for most programming languages and many ciphers require multiple iterations and even processing power. Now a day’s early school kids crack codes like this with ease. It’s a basic form of encryption where the letters were simply shifted by 3 back down the alphabet.

Julius Caesar used this to hide military messages. One of the earliest known ciphers is Caesar Cipher.

Encrypting and decrypting messages is a lot of fun.Ī cipher is a series of steps taken to encrypt or decrypt a message that you might want to hide. Often solving clues involves decrypting some sort of hidden message. Cryptography is the art of writing and solving clues. Over the last few months, I have found myself interested in cryptography.
