Hi Raul,
Could you please provide us with the text of the error you get?
The component supports GZip.
I would recommend you checking our CSV Compressor. It is available for .NET, Java and PHP and its newest version can be downloaded together with the front-end component from
Also, I would recommend you reading the blog post OLAP vs CSV: What to Choose to Boost Your Pivot’s Performance

Hi Raul,
It looks like your file is too large to store in the browser’s memory. In this case, I can recommend you to prefilter your data and split it to smaller chunks.

Hi Irina,
But the description of the grid Says that support 100Mb of CSV data, i think that can do.
How i split in parts the ocsv data and how i pass it to the grid?
Thanks for your help.

Yes, you are right, the description says 100Mb of CSV but it doesn’t say the same about compressed data. I suggest using the server-side prefiltering tool. It will help you to reduce the amount of loading data.

Best regards
