CSVbox
The Fast CSV Importer for Modern SaaS Teams
CSVbox is an embeddable importer widget for web apps and SaaS products that adds spreadsheet import functionality without building a parser, mapping flow, and validation layer in-house. Users upload files in the browser, map columns, and correct errors before validated data is delivered to a webhook, API, or database.
The widget supports CSV, Excel, PDF, image, and document files, with AI-powered column mapping, AI Pre-Import Transform for restructuring files from plain-English instructions, built-in and custom JavaScript validation rules, server-side checks, and server-side transforms. Delivery connects to destinations including Postgres, MySQL, Airtable, Google Sheets, Zapier, and n8n. SDKs are available for React, Angular, and Vue.js, alongside a plain JavaScript snippet, plus a REST File API and an MCP server for AI clients. Features include import analytics, theming and internationalization, Private Mode for browser-only processing, data residency options, and SOC 2 Type II and GDPR compliance.
CSVbox is aimed at developers and product teams adding data onboarding to their applications. It is packaged with a free Sandbox plan with monthly import and row limits, and paid plans that scale with rows imported rather than seats, with per-import row caps varying by tier.
