Google Sheets has a maximum cell limit of 10 million cells, but this doesn't necessarily mean having that many cells is useful or practical. The increased limit allows for more data storage and manipulation possibilities, including the ability to create large datasets for record-keeping or analytics projects. However, with such a large number of cells, Google Sheets can become slow and unresponsive, especially when using certain formulas or functions. Additionally, this limit can cause issues with automation tools like Zapier, which may experience timeouts or errors. To make the most of the new limit, it's recommended to use alternative solutions like databases or specialized apps like Airtable, which are designed for handling large datasets and offer improved performance and collaboration features.
