High Memory Usage Issue

[aleql]

My issue is that i need to generate an Excel file of around 230000 rows, which with the gem Axlsx consumed a large amount of memory, roughly 4 GB. I tried to change my app to use RubyXL Version 3.4.6 expecting to improve memory performance but it remained almost the same.
Am I using the a wrong version or this high memory usage is an expected performance?
Thanks in advance

I have the same issue. Did you find out a way to decrease memory consumption?

Same here, for about 4000 rows. Is there a workaround by batch writing rows?

consider to use this guys https://github.com/Paxa/fast_excel
its backend using C so it should be fast
