Sheetson vs Sheet2API: Which Google Sheets API Is Better in 2026?
Sheetson and Sheet2API both turn spreadsheets into REST APIs, but they differ on two axes: price and spreadsheet scope. Sheetson is Google Sheets-only with a permanent free tier and flat $9.99/mo pricing. Sheet2API supports both Google Sheets and Excel Online but starts at £29.99/mo ($38 USD) with a limited 500-request free tier.
If you need Excel Online support, Sheet2API is the only option between the two. If you only need Google Sheets, Sheetson is significantly cheaper at every usage level.

Features
Sheet2API's standout feature is Excel Online support. If your data lives in Excel spreadsheets hosted on Microsoft's platform, Sheet2API can expose them as a JSON API. No other major tool in this comparison covers Excel. Sheet2API also offers real-time updates, intelligent caching, custom domains on paid plans, and an HTML form-to-Sheet integration for collecting submissions.
Sheetson is Google Sheets-only. It covers full CRUD, WHERE-clause filtering, pagination, OAuth2 authentication, and API key management. It does not offer real-time updates, intelligent caching, custom domains, or HTML form integration.
Neither tool offers server-side aggregation or pivot queries — that's Sheet.best's territory, not theirs.
Pricing
Sheet2API's pricing is in GBP, which adds friction for USD users. Free is 500 requests/month. Starter is £29.99/mo ($38 USD) for 5 APIs and 10K requests. Pro is £49.99/mo ($64 USD) for 20 APIs and 50K requests. Elite is £129.99/mo ($166 USD) for 50 APIs and 500K requests. There's also a Lifetime option at £249.99 ($320 USD one-time).
Sheetson is $0 or $9.99/mo. The paid plan includes unlimited rows, 1,000 rows per request, and higher rate limits. No tier counting, no API count limits.
Sample workload: 10K requests/month across 3 sheets. Sheet2API Starter at £29.99/mo ($38 USD) covers 5 APIs and 10K requests. Sheetson paid at $9.99/mo covers it with unlimited rows. Sheetson is 3.8x cheaper.
Workload: 50K requests/month across 10 sheets. Sheet2API Pro at £49.99/mo ($64 USD) covers 20 APIs and 50K requests. Sheetson paid at $9.99/mo. Sheetson is 6.4x cheaper.
The math is consistent: unless you need Excel support, Sheet2API's pricing is hard to justify against Sheetson's flat $9.99/mo.
Performance and limits
Sheet2API caps both API count (5–50) and monthly requests (10K–500K) by tier. The free tier's 500 requests/month is tight — enough for testing but not for a live project with any traffic.
Sheetson's paid plan has no row cap and a 1,000-row-per-request limit. There's no published monthly request cap on paid plans; you work within rate limits. Sheetson's free tier allows 1,000 rows per sheet and 100 rows per request — more generous than Sheet2API's 500-request free tier for most use cases.
Ease of use and setup
Both tools follow the connect-spreadsheet-get-endpoint pattern. Sheet2API supports both Google Sheets and Excel Online, so setup differs by spreadsheet type. Its documentation covers both paths.
Sheetson uses OAuth2 for Google authentication, which is more secure than API-key-only connections. API keys handle request auth. Setup is connect → generate key → start making requests.
Sheet2API's GBP pricing and tier structure add decision overhead. Sheetson's two-plan structure (free or $9.99/mo) is simpler to reason about.
Support and docs
Sheet2API offers setup support on paid plans and a 30-day money-back guarantee. Its documentation covers both Google Sheets and Excel Online integration. It's listed on SaaSHub and SaaSWorthy (73% SW Score).
Sheetson ships developer-focused documentation with REST endpoint references, filtering syntax, and pagination examples. Support is available on both free and paid plans.
Who Sheetson is best for
- Developers who only need Google Sheets (not Excel)
- Anyone who wants a free tier that handles real development, not just 500 requests
- Teams that prefer USD flat pricing over GBP tiered pricing
- Projects where $9.99/mo with unlimited rows is the right economic model
Who Sheet2API is best for
- Teams that need Excel Online API support (Sheetson can't do this)
- Users who want a lifetime access option and are willing to pay £249.99 upfront
- Projects that need real-time updates or intelligent caching
- Teams that need HTML form-to-Sheet integration
Migrating from Sheet2API to Sheetson
- Verify your spreadsheets are Google Sheets. Sheet2API supports Excel Online; Sheetson does not. If any of your APIs point to Excel files, migrate them to Google Sheets first or keep those on Sheet2API.
- Connect your sheets to Sheetson. Authenticate with OAuth2 and generate API keys for each environment.
- Map your API calls. Sheet2API's search/filter syntax translates to Sheetson's WHERE-clause filtering. Update base URLs and auth headers.
- Replace real-time update patterns. If you relied on Sheet2API's real-time updates, switch to polling with Sheetson's pagination. The 1,000-row-per-request limit on paid plans supports efficient polling.
- Handle custom domains. Sheet2API's custom domain feature has no Sheetson equivalent. You'll access Sheetson's API via its standard endpoints.
- Cancel Sheet2API after verification. Test your integration end-to-end first. The 30-day money-back guarantee gives you a window to evaluate.
