Google Sheets is the spreadsheet app available on Google Workspace, or standalone, with a free plan for personal use and accessible via mobile apps for iOS and Android.
Google Sheets is great for just recording tabular information that needs to be shared with and/or edited by multiple people. Sharing and collaborating is especially convenient because Sheets is designed to be browser-based; while Excel has a browser version, it's limited compared to the desktop app. Google Sheets's editing, suggesting, commenting, and viewing permissions settings are absolutely perfect for my department. Google Sheets does not handle large datasets well. It does not load in a timely manner and often freezes. Apps Scripts fail to process large amounts of data.
Overall the formula functions could improve but there's workarounds for them. Utilzing different formulas or approaches for building out accounting schedules. While collebrating with multiple team members and different departments being able to go in and see where others are on the sheets is helpful. Google Sheets overall is a great product
Like most Google products, Google Sheets rarely has outages or slowness, and when it does, connection is always momentarily restored. I can't recall a time when I've been unable to access Google Sheets but able to access other sites just fine. That said, errors aren't uncommon when handling large data volume. You know what they say about using spreadsheets as databases, but sometimes it's just the most convenient option, especially for smaller or one-off projects, and not being able to store large amounts of data hampers our ability to move quickly with scrappy prototypes or full solutions. It would be great if we could better integrate our data manipulation (Apps Script) with big data in the sheet.
Again, Google Sheets is no exception to Google's general high speed and reliability, but load times can be slow for larger amounts of data. I've used Sheets with Zapier and have used the Python API, and speed has never been an issue.
I have never contacted Google Sheets support, but Google Sheets makes it very easy to report an issue or suggest a feature from Sheets itself (Help > Help Sheets improve), and I've had mostly good experiences with support for other Google products.
The major reason I use Google Sheets over Microsoft Excel and Apple Numbers is for its ability to allow multiple users to access and work on the same spreadsheet at once. This is incredibly more efficient and effective than updating and sending copies upon copies of the same Excel or Numbers spreadsheet back and forth as email attachments.
I'm not involved with the purchase, but I assume everything goes smoothly and that the pricing structure is predictable and reasonable. We do not get surprise fees.
Google Sheets works very well with multiple users. It's convenient to see in real-time who is collaborating in a sheet, down to the specific cell that they're viewing/editing. Linking Sheets across departments is convenient with the IMPORTRANGE function.
