Google Sheets – Where Does the Calculation Take Place?

google sheetsgoogle-sheets-performance

In Google Sheets I have quite a large number of relatively complex array formulae in many cells that takes ages to complete calculating.

Does the speed of calculation depend on my PC resources, or are calculations processed in Google's servers?

Best Answer

Short answer

The recalculation speed depends mostly on the local resources.

Explanation

On Google Sheets, most of the built-in functions are run on the client (browser), just some functions like IMPORTHTML, IMPORTXML, IMPORTDATA, IMPORTRANGE, GOOGLEFINANCE require access to the Internet in order to be executed, as well the custom functions because they require Google Apps Script which is run on the Google servers.

You could use something called Google Chrome timeline-tool to check your specific case.
