Hands-on ChatGPT in Excel (Book)

Excel is a suprisingly simple and effective tool to create solutions that make use of Generative AI.

In this book you will learn everything you need to know to create your own AI-infused Excel tools:

1. How to use the new LABS.GENERATIVEAI Excel function,
2. How to prompt ChatGPT to get results you can work with in Excel, and
3. How to use a hand full of other Excel functions to create prompts and work with completions.

You can buy this book on Amazon.

You can also buy my course ChatGPT for Excel Users which covers the same topics.

Here are the Excel workbooks referenced in the book. You can download them individually or as a single zip archive.

Getting Started and Creating Prompts with Excel Formulas

Download Link	Description
chatgpt-capabilities.xlsx	A framework to think about ChatGPT’s capabilities. Main point: ChatGPT is not only about creative writing.
concatenating-text.xlsx	Shows how to create prompts for ChatGPT in Excel with text concatenation.
converting-numbers-to-text.xlsx	Shows how to convert numbers, dates, and times to a format that you can use in ChatGPT prompts.
joined-lists.xlsx	How to join lists in Excel so that the data can be used in ChatGPT prompts.
markdown.xlsx	Demonstrates joining tabular cell ranges into a CSV table that ChatGPT can understand. ChatGPT converts Excel tables to Markdown tables.
largest-capital.xlsx	Demonstrates joining tabular cell ranges into a single CSV String with the TEXTJOIN Function. In this example, the data is added to the prompt that asks ChatGPT to select the largest capital in terms of population relative to the country’s population.
text-topic-verification-tool.xlsx	A workbook prepared for the lab about Text Topic Verification. The task is to convert a prompt template into a valid Excel formula. The tool can check if a text is about a given topic. This works even if the word for the topic is not mentioned in the text.
text-topic-verification-tool-solution.xlsx	A solution for the Text Topic Verification lab.

cities-list.xlsx	Prompting ChatGPT to generate lists for Excel.
fruits-table.xlsx	Prompting ChatGPT to generate tables for Excel.
date-transformer.xlsx	A workbook prepared for the lab about date transformation.
date-transformer-solution.xlsx	A solution for the lab about date transformation.
sentence-generator.xlsx	A workbook prepared for the lab about sentence generation.
sentence-generator-solution.xlsx	A solution for the lab about sentence generation.
sentence-generator-solution-improved.xlsx	An improved solution for the lab about sentence generation.

Adding Logic to Prompt Flows in Excel

Download Link	Description
prompt-preparator.xlsx	Demonstrates letting the user decide what to do next by asking the user to decide if the app should start prompting.
logical-functions.xlsx	Shows the effect of the XOR, AND, and OR functions on four variants of input values as well as the result of the NOT function on the result of the OR function.
comparison-operators.xlsx	Shows the effect of the six comparison operators on three variants of input values.
combo-compass.xlsx	Demonstrates the use of logical functions and the IF functions to let Excel decide what to do next.
grammar-genie.xlsx	Demonstrates the use of a ChatGPT result in the condition of an Excel IF function.
dreamfit.xlsx	Demonstrates the use of lookup tables together with the XLOOKUP function to look up parts of a prompt for ChatGPT.
opti-response.xlsx	Demonstrates a parallel prompt flow in Excel. The workbook contains an input cell for customer feedback and a list of products. The workbook uses parallel prompt flows to infer the sentiment and the product mentioned in the feedback. Then, it uses the results to generate a positive response.
context-check.xlsx	Demonstrates that LABS.GENERATIVEAI only forwards information to ChatGPT that you provide via the prompt attribute. It does not keep context information on its own.
chatsheet.xlsx	Demonstrates how to build a chat sheet in Excel.
tablejoin-function.xlsx	An Excel workbook that contains the TABLEJOIN Excel LAMBDA function and an example how to use it. You can use the TABLEJOIN function to join tabular cell ranges into a CSV table with a single function call.
data-dynamo.xlsx	Contains an Excel LAMBDA function for creating example data with the help of ChatGPT.
slogan-sheet.xlsx	A workbook prepared for the lab about creating Slogan Sheet. This can help you come up with and evaluate creative slogan ideas and is an example of a multi-step prompt flow in Excel.
slogan-sheet-solution.xlsx	A solution for the Slogan Sheet lab.

Advanced Prompt Engineering Techniques for Excel

Download Link	Description
number-extraction.xlsx	Demonstrates few-shot prompting with Excel and ChatGPT by extracting numbers from text.
sentiment-classification-few-shot.xlsx	Demonstrates few-shot prompting with Excel and ChatGPT by classifying the sentiment of a text.
sentiment-classification-zero-shot.xlsx	Shows that ChatGPT can classify the sentiment of a text with zero-shot prompting, too.
reasoning-extraction-with-cot.xlsx	Demonstrates chain-of-thought prompting for improved reasoning capabilities. ChatGPT solves a text challege. The resulting number is extracted with a second prompt. I found this example in the paper When do you need Chain-of-Thought Prompting for ChatGPT? by Chen et al, 2023. I used it as it nicely compares chain-of-thought with zero shot reasoning.
reasoning-extraction-without-cot.xlsx	Demonstrates that ChatGPT can solve the challenge also without chain-of-thought prompting. This shows that you do not always need to add the magic “let’s think step by step” phrase to your prompts to get good results.
are-you-open.xlsx	Demonstrates retrieval augmented generation (RAG) with Excel and ChatGPT.
simupy.xlsx	Demonstrates the “acting” prompt engineering technique by letting ChatGPT act as a Python interpreter. With this, you get a simulated Python interpreter in Excel.
flash-function.xlsx	A workbook prepared for the lab about creating FLASH - a ChatGPT powered flash fill implemented as an Excel LAMBDA function.
flash-function-solution.xlsx	A solution for the FLASH lab.
