About ExcelFormulaAI
Student-built spreadsheet tools and error guides · Hyderabad, India
ExcelFormulaAI is a free learning project by Nikhil Kappagantula, a student in Hyderabad, India, building practical Excel & Google Sheets tools with AI.
The goal is simple: help students, analysts, and everyday spreadsheet users fix formula errors faster, understand why something broke, and ship cleaner workbooks — without drowning in forum threads.
What you get here
- Formula Studio — describe what you need in plain language and get Excel/Sheets formulas.
- Error Directory — searchable diagnostics for #SPILL!, #N/A, #VALUE!, #REF!, VBA errors, and more (100+ quick-fix cards with deep-dive guides).
- Deep guides & playbooks — step-by-step fixes for real spreadsheet problems.
- Data Studio — tools for exploring and cleaning sheet-style data in the browser.
How it’s built
Most interactive tools run client-side in your browser. Your spreadsheet data is not uploaded to our servers for formula generation. Guides and static pages are educational content only.
This site is actively maintained as a learning + product experiment. Features and pages improve continuously.
Who’s behind it
Nikhil Kappagantula — student learning to build with AI, based in Hyderabad, India. ExcelFormulaAI is the public home for that work.
