Excel Astrology — Build Your Own Calculators
Build astrology calculators with Excel, Google Sheets, and Swiss Ephemeris. Prototype your ideas quickly, work offline, and create tools that help you learn and practice Vedic astrology — no coding required.
Why Build with Spreadsheets?
Works Offline
Once set up, your spreadsheet calculators work without internet. Carry your astrology tools anywhere on your laptop.
Prototype Ideas Fast
Quickly test astrology logic in a spreadsheet before building full tools. Perfect for validating formulas and calculations.
Swiss Ephemeris Accuracy
Use Swiss Ephemeris data for precise planetary positions. The same engine used by professional astrology software worldwide.
Google Sheets — Share & Collaborate
Build in Google Sheets to share calculators with your astrology community. Everyone can use and learn from your work.
How It Works
Get Planetary Data
Download Swiss Ephemeris tables or use online APIs to get accurate planetary positions for any date, time, and location.
Set Up Your Spreadsheet
Create sheets for input (birth details), planetary data, and output (charts, dashas, yogas). Use formulas to link everything together.
Build Calculations
Implement astrology logic — house cusps, planetary aspects, dasha periods, sign placements, nakshatras, and divisional charts using spreadsheet formulas.
Test & Iterate
Validate results against known charts. Refine your formulas, add new features, and expand your calculator step by step.
