About THREDr

Who We Are: THREDr LLC is an authorized Microsoft Partner/Developer dedicated to unlocking the full potential of Excel as a modern application platform. We bridge the gap between traditional spreadsheet workflows and contemporary application development — enabling organizations, consultants, and developers to build scalable, real-time, and data-driven solutions inside Excel. Our flagship product, THREDrDB, is an Office.js (Node.js) add-in written in TypeScript that seamlessly extends Excel’s formula and calculation engine. Designed for speed, flexibility, and innovation, THREDrDB reintroduces Excel as a viable interface for modern application logic — without sacrificing the familiarity users depend on. Our Mission: To empower professionals, analysts, and developers to transform Excel from a static calculation tool into a live, asynchronous, and integrated data processing platform — no-code required. We believe the best tools are those people already know how to use. By enhancing Excel rather than replacing it, we help clients unlock new capabilities without retraining entire workforces or abandoning legacy workflows. THREDrDB: What It Does THREDrDB adds a suite of asynchronous worksheet functions that integrate directly into Excel’s formula ecosystem. These functions operate in-memory using SQLite and are designed to feel like a natural extension of Excel — but with powers far beyond its native capabilities. * Live, Asynchronous Data Processing — Avoid traditional recalculation bottlenecks with async execution that keeps your workbook responsive. * Embedded SQL Queries — Run complex queries directly within Excel formulas, leveraging an in-memory SQLite database for lightning-fast performance. * API Integration — Connect to REST APIs using GET or POST requests, parse JSON results, and load them directly into worksheets or the in-memory DB.
