GRID vs AskCSV

GRID is a spreadsheet engine for developers embedding Excel-grade calculations and sheet UI inside their own products. Install @grid-is/spreadsheet-engine from npm and run recalculation in the browser, on Node.js, on-device, or on your own infrastructure. The companion @grid-is/agent-tools package exposes 27 MCP-ready tools so agents load .xlsx files, trace precedents, edit cells, and goal-seek without writing Python each time.

Generic spreadsheet libraries leave you wiring cell reads by hand, and agents that generate openpyxl scripts burn tokens while guessing at formula dependencies. GRID pairs a deterministic recalculation core with structured tool calls, which is why its agent setup scored 91.25% on SpreadsheetBench's expert-verified 400 tasks while a code-generation approach on the same goal-seek demo needed 3,240 tokens versus 86.

Software teams building SaaS dashboards, Excel add-ins, or LLM products use GRID's headless engine plus optional Spreadsheet Viewer and Editor React components when humans need a familiar sheet surface. Customers cited on grid.is include major investment banks and a leading LLM provider. Every npm package ships with a free evaluation license; commercial licenses apply when you ship to customers.

AskCSV runs CSV and TSV analysis entirely in your browser. You drop a file, ask business questions in plain English, and get tables or charts without uploading spreadsheet rows to AskCSV servers. It targets anyone who wants Excel-style answers from tabular exports while keeping revenue, customer, or HR data off shared infrastructure.

Most AI spreadsheet tools route your file through cloud models. AskCSV keeps the query path local instead. An on-device AI turns questions into SQL, DuckDB runs the query in the browser, and only app assets plus the cached model use the network. That trade-off means a one-time 1.8 GB model download and WebGPU browser requirements, but the site documents a verifiable zero-upload path you can confirm in DevTools.

Pro at $5 per month adds unlimited successful analyses, ZIP and chart PNG exports, deterministic two-file join or stack, and an ad-free interface. The free tier still covers 10 successful analyses per month with no account required, though ads fund that plan. Failed query attempts do not consume the monthly analysis counter.

The workflow fits analysts, marketers, and small business owners who work with sales exports, customer lists, or operational spreadsheets and need quick charts without building pivot tables. Google sign-in is only required when upgrading to Pro, with billing handled through Stripe while file data stays in the browser.
