What is Ivandt used for?

Ivandt handles bulk upload, bulk forms, and data migration. Stop rebuilding one-off data uploaders. Define validation rules once, reuse everywhere. Perfect for onboarding customer data, migrating between systems, or any scenario where you need to move lots of data at once.

What file formats does Ivandt support for bulk upload?

Ivandt supports Excel (.xlsx, .xls), CSV, JSON, PDF, and plain text files for bulk upload and data migration. The SDK can handle files with millions of rows and cells, processing everything client-side for maximum privacy and performance.

How fast is Ivandt for bulk data validation?

Ivandt validates up to 1,000,000 cells per second using web workers for parallel processing. A file with 500,000 rows and 10 columns (5 million cells) is validated in about 5 seconds, entirely in the browser.

Do I need to rebuild my data uploader for each use case?

No. With Ivandt, you define validation rules once and reuse them everywhere. Create templates for different data types (customers, products, transactions) and use the same SDK across your entire application. Stop rebuilding uploaders.

Which frameworks work with Ivandt?

Ivandt provides native components for React, Vue, Angular, and Svelte. It also works with vanilla JavaScript and can be embedded in any web application for bulk upload and data migration.

Is Ivandt secure for bulk data migration?

Yes. Ivandt processes data client-side by default, so sensitive information never leaves the user browser during bulk upload or migration. The platform is built on SOC 2-certified infrastructure and is GDPR, CCPA ready, and HIPAA-eligible.

What is the difference between Ivandt and Flatfile?

Ivandt processes data entirely client-side for maximum privacy and performance, while Flatfile requires server-side processing. Ivandt validates 1M cells/sec, offers native components for all major frameworks, and lets you configure once and reuse everywhere. Better for bulk upload, bulk forms, and data migration.

Bulk Upload & Data Onboarding

The hidden cost of "simple" file uploads

If your app deals with customer data, eventually your users will want to bring their own data in bulk. They don't want to fill forms one by one.

New Feature Request #2491

John Doe (Customer)

Sent via Intercom • Just now

We love the product, but adding users manually is impossible for us. We have 5,000 records in Excel.

Can we just upload our spreadsheet?

The "Weekend Project" Plan

It sounds simple enough. You just need a file input and a table.

Just create a table with some inputs
Let users upload a CSV file
Parse the rows and save to DB
Add a few validation rules
Done in a sprint, right?

But reality hits hard.

Months of resources wasted because it's way more complicated than you thought.

Browser crashes rendering 5,000 rows (need virtualization)

Users upload 'Given Name' but your DB needs 'firstName'

Header detection is a nightmare (Row 1? Row 2?)

Complex cross-field rules (If A then B, unless C...)

Dates come in mixed formats (MM/DD vs DD/MM)

Keyboard navigation & accessibility are missing

Adding one new field breaks the entire import script

Now you have to build it again for the next feature...

Encoding issues break special characters

Validation errors need to be shown per cell

User wants to paste from clipboard

Need to support XLS, XLSX, CSV, TSV...

What if the file has merged cells?

Data Migration & ETL

Stop writing throwaway ETL scripts.

Need to ingest a monthly Xero export? Migrating a new client's legacy CRM data?
Building custom scripts for every new file format is a maintenance nightmare.

The Hidden Cost of Custom Scripts

Fragile Scripts

One unexpected null value or a format change breaks your entire script, forcing your senior engineers to drop everything and debug.

Hidden Errors

Scripts fail silently. Without a proper validation UI, bad data slips into your production database, causing support tickets weeks later.

Endless Maintenance

Every new client brings a new file format. You spend more time maintaining "Data Janitor" scripts than building your core product.
