Modern data onboarding SDK for importing, validating, and transforming structured data
What is Ivandt Importer?
Ivandt Importer, is a modern, high-performance, embeddable data onboarding SDK that enables businesses to import, validate, transform, and deliver structured data directly inside their applications. It replaces messy, error-prone spreadsheet uploads with a controlled, schema-driven pipeline that ensures every record matches your business expectations before it hits your backend systems.
At its core, the Importer is a web component that works in any framework — React, Angular, Vue, Svelte, or vanilla JavaScript. It handles file parsing, intelligent column mapping, real-time validation, data transformation, and provides an Excel-like review interface for users to fix errors before submission.
The import flow
Here's what happens when a user imports data:
Upload
User uploads Excel, CSV, TSV, or JSON file. Ivandt supports multiple file formats and handles large files efficiently.
Parse
Ivandt parses the file using web workers for performance. This keeps the UI responsive even with massive datasets (500k+ rows).
Map
AI-powered column mapping automatically matches spreadsheet headers to your schema fields. Users can manually adjust mappings if needed.
Validate
Every cell is validated against your rules in real-time. Validation runs in parallel across multiple web workers for speed.
Transform
Data is cleaned and transformed according to your configuration. Transformers run automatically or can be triggered by users.
Review
User sees an Excel-like interface to review and fix any errors. Inline feedback, smart fix suggestions, and bulk correction tools make fixing errors fast.
Submit
Clean JSON is generated and sent to your onSubmit handler. You receive validated, transformed data ready for your database.
