Spreadsheet and operational table APIs for AI agents
Spreadsheets and table products an agent can read and write. Cells, ranges and formulas in a workbook, or typed records in a base. Compared on read and write calls, batch limits, formulas, change events and how access to one file is scoped.
Capability keys sheets.read · sheets.write · sheets.tables · sheets.formulas · sheets.records · All tools
letme.dev/sheets.read picks the top-graded tool in this list and says how to call it direct; calling through letme comes later.
The same listing from the live API. Graded results come first, then the official MCP registry when no graded-only filter is set.

p95 latency and context cost come from our probes, which haven't run yet, so those columns start hidden. Grades run from AA to F, and agent-ready means BB or better. Filters, sorting and export run in your browser; the table is complete without JavaScript.
How we test this category
The same workbook of one thousand rows in each listing. The same tasks run through its API (read a range, append rows, update cells in a batch, add a formula column, filter records). We check limits, consistency after writes and change notifications. In this run listings are graded from public evidence against the published checklist. This test hasn't run yet, so Task success is pending and the grades here come from the categories assessed from public evidence.
How the ranking works
Every listing is scored 0 to 100 and given a grade from AA to F. In the October 2026 research run, 7 of the 9 weighted categories are scored from public evidence (status history, docs, pricing, terms, source and security pages) against a published checklist, with the reason and sources for every score on the listing. Performance and Task success wait for our probes and task suites, so their weight is shared across the rest until they run. Negative events deduct up to 15 points. Read the methodology.
For companies
Do agents find, use and choose your tools?
An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
