Ivandt is a high-performance data onboarding SDK for modern apps. Embed a native importer (no iframe) to handle messy CSV/Excel entirely in-browser with web workers, schema-based or schema-less + AI type detection, powerful validation and transforms, Smart Fix suggestions, and flat pricing with unlimited imports.
This addresses a universal dev headache. Moving validation and cleaning to the browser with web workers is the right architectural choice for performance and cost.
A key technical question: How does the SDK handle truly massive files (e.g., 500MB+ CSV) in the browser? Does it implement chunked processing or streaming to prevent browser tab crashes, or does it have a recommended fallback to a server-side flow?
Hi @olajiggy321
Absolutely, chunking and parallel processing is at the core of our SDK. Every single line of the code is scrutinised to be performing well under pressure. Smallest thing like favouring "for loops" over "maps", to bigger things like handling millions of cell validation and transformation off the main threat and in parallel, aggressive caching, smart reusing of the results and much.
Regarding 500mb+ csv, if your browser can actually manage to accept a large file as an input, then our SDK can perfectly handle it. We've tried cases where we've generated a 500k rows*10 cols ( 5m cells ) Excel file, and tried to open it to edit it in a high performing Mac, funny enough, the Mac's Numbers app actually crashed, while you can upload the file to our SDK and it will perfectly handle it !!!
With CSV files, our SDK is even incredibly faster, since CSV can perfectly be chunked and it doesn't have the heavy meta information that a typical Excel file would have.

Thanks for the detailed breakdown. The focus on low-level optimization (for loops vs maps) and parallel processing is impressive—it shows the depth.
It gave me a small, practical idea on how to communicate that raw performance advantage more viscerally to developers on your landing page. Something you could try on your own.
Best way to send it over?
Hi @olajiggy321
I'm not sure what you mean, are you suggesting you're designing something that you can send over ?
If so, you can send it to support@ivandt.com
@ivandt
sent you the idea
I tried the CSV editor free tool ( https://www.ivandt.com/tools/csv-editor) ;
It's actually pretty amazing and accurate. The fact that it demonstrates the Ivandt SDK while offering a free tool to the community is really nice.
I think the video on the landing page could be improved, it doesn't tell much of the functionalities that the SDK has
