Our role

Where product engineering meets operational reality.

Pagos is the company behind SpreadsheetWeb. We bring product development, implementation experience, and long-term stewardship together around one focused platform.

Product development

We design, build, and maintain SpreadsheetWeb as a dependable platform for business-critical spreadsheet processes.

Experience across industries

Spreadsheets are used in every industry, and Pagos has worked with organizations in almost every sector. That breadth helps us understand the many ways calculation logic, data, workflow, and governance come together.

Business and IT alignment

Our approach keeps subject-matter experts close to the logic they know while giving technical teams a controlled application environment.

Long-term stewardship

We invest in continuity: preserving valuable models, supporting changing requirements, and advancing the platform without abandoning the knowledge already embedded in Excel.

SpreadsheetWeb

The platform at the center of our work.

SpreadsheetWeb converts complex Excel spreadsheets into secure, scalable web applications and APIs without requiring formula rewrites. Existing models remain the source of calculation logic while the surrounding process becomes easier to control, use, and extend.

Preserve proven logic

Keep formulas, calculations, and dependencies intact instead of recreating complex models in traditional application code.

Centralize control

Replace distributed spreadsheet copies with managed access, consistent versions, structured data, and visibility into how applications are used.

Connect and automate

Build purpose-specific interfaces, save records, generate documents, send emails, and expose calculation logic through APIs for other systems.

Product history

The SpreadsheetWeb platform grew from an established spreadsheet calculation engine and years of production implementation experience.
