Inspiration

Spreadsheets are powerful but often frustrating tools. They require users to memorize complex formulas and spend time on tedious formatting, leading to a slow and efficient process. We wanted to create a solution that enhances productivity, reduces errors, and makes spreadsheets smarter and more intuitive.

What it does

LeXcel is an AI-powered add-on that enhances traditional spreadsheets by:

Simplifying complexity – Enables users to generate complex formulas using natural language prompts
Eliminating tedious formatting – Structures and formats new data given user requests
Iterating With Verification – Learn from previous mistakes to produce consistent and robust solutions

How we built it

We developed LeXcel as a seamless add-on in Google Sheets that is easy to download and run for anyone: no coding experience required. Our main tech stack is javascript, google script, sheetAPI, OpenAI, and Gemini.

Challenges we ran into

Ensuring AI suggestions are accurate and context-aware for different spreadsheet use cases
Building a UI/UX that integrates seamlessly without disrupting existing workflows

Accomplishments that we're proud of

Built a user-friendly AI-powered assistant that significantly reduces the time needed for spreadsheet tasks
Successfully implemented real-time error detection and reasoning to fix its own errors

What we learned

There is a tradeoff between AI automatically inputting all formulas which may feel like magic, versus prompting the user for confirmation which could lead to more consistent results

What's next for LeXcel

Allow LeXcel to manipulate delete/insert rows, move data around, etc.
Give LeXcel the ability to generate and execute multi-step computations
Tackle more complex puzzles and Excel World Championship tasks
Integrating with more spreadsheet platforms beyond Google Sheets such as Paradigm and Excel
