Oneschema

OneSchema is an embeddable data onboarding and file-import platform for developers. Its core Importer embeds a guided CSV and spreadsheet upload experience — file upload, header detection, AI-assisted column mapping, and row-level validation against reusable Templates — directly inside a customer-facing product, so end users import clean, schema-compliant data in minutes. Beyond the embedded Importer, OneSchema offers Multi FileFeeds for automating recurring, transformation-heavy file ingestion pipelines (SFTP, S3, Google Drive/Sheets, Salesforce, SQL sources; AI file and PDF transforms; validation and delivery), a REST API at api.oneschema.co for headless importer sessions, templates, sheets, webhooks and connections, first-party JavaScript/React/Angular/Vue SDKs, and a hosted MCP server for AI coding assistants.

Oneschema publishes 28 APIs on the APIs.io network, including AWS Secrets Manager Accounts API, AWS Secrets Manager Secrets API, Azure Key Vault Accounts API, and 25 more. Tagged areas include Company, Data Onboarding, CSV Import, Data Validation, and File Processing.

The Oneschema catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Oneschema’s developer surface includes authentication, documentation, API reference, getting-started guide, engineering blog, support, pricing, and 29 more developer resources.
