Example Usage & Test Cases

How It Works

1

Keeps the grid in memory as cells addressed like A1 and B2. A new sheet starts with 10 columns (A to J) and 30 rows, and you can add more rows and columns.

2

Evaluates arithmetic expressions and the functions SUM, AVERAGE, MIN, MAX and COUNT over a cell range, and flags circular references instead of crashing.

3

Exports the evaluated grid as a genuine .xlsx workbook (with real numeric cell types, not text) or a standard RFC 4180 CSV file.

Frequently Asked Questions

Supports =SUM(start:end), =AVERAGE(start:end), and arithmetic operations like =A1+B1, =B2-C2, =A1*1.15, =A1/C1.

Good to Know

Common uses

  • Quick budgets and lists with basic formulas
  • Tidying small CSV-style data

Limitations and notes

  • The grid auto-saves in this browser's local storage only; export a copy to keep it safe.
  • It supports common formulas, not the full range of Excel functions, pivot tables or macros. Check results on important sheets.
