What API Spreadsheets does
API Spreadsheets, operated by Woyera, Inc. (a privately held Delaware corporation founded in 2023) and based in New York, is a cloud-based API platform that exposes spreadsheets—Excel, CSV, and Google Sheets—as programmable endpoints. The core product comprises /data (RESTful CRUD and queries), /calculate (on-demand execution of spreadsheet formulas and macros), /import (file intake, validation, cleaning, and routing), /ai (natural-language CRUD), and /agents (deployable conversational agents), supplemented by Custom APIs, an Agent Builder, MCP Server integrations for Claude and Cursor, and official Python and JavaScript/TypeScript SDKs. Architecture is API-first with OpenAPI spec publishing, webhooks for row events, custom-domain hosting, and enterprise-grade security including TLS 1.2+/AES-256 encryption, SOC 2, ISO 27001, GDPR compliance, and on-prem deployment options.

- Analysis Endpoint AI-generated analysis endpoint that returns narrative summaries plus structured JSON with trends, outliers, and key statistics for any spreadsheet file. Supports configurable focus areas across Excel, CSV, and Google Sheets.
- Rules Engine Centralizes business logic in spreadsheets and exposes it as a compute API. Configures typed inputs/outputs, versions rules, and evaluates decisions consistently across applications for finance, insurance, and operations teams.
- Analytics Builds live KPIs and dashboards from spreadsheet data by connecting Google Sheets or Excel, defining metrics via configuration, and sharing via API or embedded iframe for internal and external reporting.
- Excel Importer API-based spreadsheet import offering mapping, validation, deduplication, and routing. Configures presets once and accepts files from any source, with cleaned data landing automatically in destinations such as warehouses or CRMs.
- Web Calculators Turns spreadsheet formulas into production calculator APIs. Users upload pricing or financial models, configure input validation, and connect to websites or apps for instant results, used by mortgage brokers, insurers, and SaaS lead-gen flows.
- Web Forms Collects form submissions directly into spreadsheets with configurable validation and field types. Posts from any site or app, rows appear instantly, and webhook notifications trigger downstream workflows.
- Build Apps Uses spreadsheets as a backend for web and mobile applications. Models data in sheets, generates CRUD APIs, and connects to Next.js, React, or mobile front-ends for fast MVP and internal tool delivery.
- AI Chatbots Builds conversational chatbots powered by spreadsheet data. Configures chat endpoints and plugs into website widgets, Slack, or Intercom for natural-language data access by end users.

API Spreadsheets competitors and assessment
Company assessmentEmerging players
- NocoDB: NocoDB is an open-source Airtable alternative that provides a spreadsheet UI over any database with REST and GraphQL APIs. It competes for developer-led teams who want spreadsheet UX without vendor lock-in, similar to API Spreadsheets' positioning.
- Baserow: Baserow is an open-source no-code database with a spreadsheet-like UI and an API. It competes for teams wanting spreadsheet-style data management with self-hosting, which overlaps with API Spreadsheets' on-prem/Kubernetes deployment value prop.
- Steedos: Steedos is a low-code platform with spreadsheet-style data modeling and API-driven workflows, often deployed on-prem. It targets enterprise buyers needing self-hosted internal tools, a segment that overlaps with API Spreadsheets' enterprise on-prem positioning.
Broad incumbents
- Zapier: Zapier connects spreadsheets to thousands of apps via automated workflows and now exposes AI actions. It is a broad incumbent in the spreadsheet-integration and automation space where API Spreadsheets also competes.
- Airtable: Airtable is a no-code database with a spreadsheet UI and a mature API and automation platform. It competes for the same 'spreadsheet-as-backend' and internal-tools use cases that API Spreadsheets targets, but at much larger scale and with its own AI features.
- Make: Make (formerly Integromat) is a visual automation platform that integrates Google Sheets and Excel with thousands of apps. It competes for the workflow-automation and data-routing use cases that API Spreadsheets' /import and webhooks serve.
Direct peers
- Glide: Glide turns spreadsheets into apps and tools without code. It overlaps with API Spreadsheets' Build Apps and AI Chatbots use cases for non-developers wanting to ship spreadsheet-driven products quickly.
- Retool: Retool is a low-code platform for building internal tools and admin panels that connect to databases, APIs, and spreadsheets. It competes with API Spreadsheets' Build Apps and Rules Engine use cases for teams needing spreadsheet-backed applications.
- Sheety: Sheety converts Google Sheets into an API with REST endpoints and basic CRUD. It overlaps directly with API Spreadsheets on the core value proposition of exposing spreadsheet data programmatically to apps and integrations.
- SheetDB: SheetDB turns Google Sheets into a REST API with similar CRUD endpoints. It is the closest direct competitor to API Spreadsheets in the spreadsheets-as-API category, targeting developers and small teams building quick data backends.
