Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

CosmosDB

  • Autoscale provisioned throughput enforces a minimum of 1,000 RU/s, billed hourly whether or not the database is used
  • Provisioned throughput is charged in every region the account is replicated to, so multi region accounts multiply the RU bill
  • Storage charges cover data, indexes and backups in each replicated region
  • Egress out of Azure and between regions is charged, though ingress is free
  • The free allowance is one account per Azure subscription, limited to 1,000 RU/s and 25 GB
  • RU/s rates vary by region and are only shown through the pricing calculator rather than a flat published rate

Google Sheets

  • Performance degrades noticeably on very large or formula-heavy spreadsheets compared with desktop Excel, particularly with complex array formulas.
  • Its charting and pivot table features are less capable than Excel for advanced statistical or financial analysis.
  • Offline editing requires the Chrome browser or a specific offline-enabled setup, so it is not as seamless as a native desktop application.
  • The free personal tier has no admin controls, audit logging or data loss prevention, so it is not appropriate for regulated business data on its own.
  • Apps Script has execution time limits and quota restrictions that make it unsuitable for heavier automation workloads a dedicated backend would handle better.

Answered from the vendors’ own pages

CosmosDB: Is there a free tier for Azure Cosmos DB?

Yes, Cosmos DB offers a free tier with 1,000 RU/s of throughput and 25 GB of storage per month for the lifetime of the account, available to new accounts.

Source
Google Sheets: Is Google Sheets really free?

Yes, for a personal Google account with full functionality, subject to the 15GB Drive storage limit shared across Google services.

CosmosDB: How is Cosmos DB priced after the free tier?

Cosmos DB uses three billing models: provisioned throughput billed per request unit per second, vCore pricing for certain APIs, or serverless consumption pricing where you pay only for requests processed. Reserved capacity offers 20% discount for one year or 30% for three years.

Source
Google Sheets: Why would a business pay for something that is free?

Businesses pay for Google Workspace, which bundles Sheets with admin controls, larger storage, audit logs and support that a personal account lacks.

CosmosDB: Can I change my pricing model after choosing one?

No. Once you select a compute pricing model and API, they cannot be changed. This choice is permanent for that database.

Source
Google Sheets: Does Google Sheets work with Excel files?

Yes, it opens, edits and exports Microsoft Excel format files directly.

CosmosDB: Is there a trial period for Cosmos DB beyond the free tier?

Azure offers a 30-day free trial account for all Azure services. Additionally, Azure AI customers may be eligible for a 90-day free Cosmos DB subscription through the Azure AI Advantage program.
