sheetto

Sheetto is a lightweight, open-source data integration tool designed to connect spreadsheet data to applications and services. It provides a unified interface for reading from common spreadsheet sources and for writing into downstream targets such as JSON, CSV, databases, and REST APIs. The aim is to streamline the flow of data from spreadsheets into software systems without requiring ad hoc scripting.

Inputs and sources: Sheetto supports local files in XLSX and ODS formats, as well as remote spreadsheet sources accessed through APIs. It emphasizes data integrity through optional schema validation, type casting, and non-destructive updates.

Features: It offers data transformation pipelines, mapping rules, and a pluggable adapter system that can export data to databases, message queues, cloud storage, or other services. It includes scheduling and triggers for automating recurring tasks, as well as webhook notifications for event-driven workflows.

Architecture: The project is designed with a modular server and client libraries in several languages. It uses adapters for spreadsheet backends and data sinks, and relies on standard authentication methods alongside a role-based permission model to control access.

Usage and reception: Sheetto is intended for developers and data teams seeking to minimize manual data handoffs between spreadsheets and applications. It is commonly discussed in developer communities and used to prototype spreadsheet-driven ETL and data-collection workflows.
