Transform your Google Sheets™ into a professional development environment.

Stop wrestling with the tiny, single-line formula bar.
Formula Foundry brings "Developer-Grade" tools to your spreadsheets, making it faster and easier to write, read, and debug even the most complex formulas.

Key Features:

Advanced Formula Editor: A beautiful, multi-line IDE inside your sidebar. Features include syntax highlighting, auto-indentation, and bracket matching - no more "Formula Parse Errors" from a missing parenthesis.

The Power of Variables: Define global or sheet-level variables (e.g., @@TaxRate or @@Q4_Goal). Use them in any formula and update them once to reflect changes across your entire workbook.

Built-in AI Assistant: Stuck on a logic error? Use our integrated AI to debug, explain, or generate complex formulas from natural language prompts.

Visual Formula Builder: Build nested IF, QUERY, VLOOKUP, and XLOOKUP functions step-by-step using a visual interface. Perfect for reducing manual syntax errors. More functions are coming.

Excel-to-Sheets Translator: Effortlessly migrate complex logic from Excel. Our translator automatically handles syntax differences so your models stay intact.

Logic Documentation: Add comments and documentation to your formulas without cluttering your cells, making it easier for teammates to understand your work.

Why Formula Foundry? Spreadsheets are code. Whether you are a Financial Analyst, Data Scientist, or a No-Code enthusiast, Formula Foundry gives you the professional tools needed to build more scalable, error-free models in half the time.
