What it looks like
It looks like an office spreadsheet inside a card with rounded corners. The top bar holds the title, undo and redo buttons and currency, percent and date formats. Below it, the formula bar shows the cell address and its raw content. The grid has letters on the columns and numbers on the rows; the selection gets an outline in the accent color, indigo by default, with a small square in the corner that you drag to extend a series. When several numbers are selected, the footer shows their sum, average and count. The demo calculates a project budget with subtotals, margins and totals.
You may be looking for this if you asked for something like
- an Excel-like spreadsheet inside my web app
- a table where I can type formulas and the total updates by itself
- an editable budget on screen with automatic sums and percentages
- a financial calculator with cells that recalculate when I change a value
- an online sheet that accepts data pasted from Excel
- that little handle on the cell corner you drag to fill a sequence
- a cell grid with lookup and IF formulas without a heavy library
Also known as
- spreadsheet component
- formula engine
- Excel-like grid
- editable grid
- online spreadsheet
- spreadsheet editor
When to use
- Quotes and proposals that clients adjust while watching the total change
- Financial, pricing or margin simulators inside a product
- Back-office screens where staff paste data from other spreadsheets
- Internal tools that need real formula calculation in the browser
When to avoid
- Lists with thousands of rows, since every cell is rendered; a virtualized table fits better
- Phone-first use, as dragging a finger scrolls the grid instead of selecting a range
- Teams that expect English function names like SUM or VLOOKUP, since formulas use Portuguese names
How to ask your AI
Create a spreadsheet with formulas inside my budgeting dashboard: a formula bar, sum, IF and lookup functions with automatic recalculation, a fill handle, currency and date formats, undo and paste from Excel, plus full keyboard navigation.
With THM Componentes, you paste the full prompt from the catalog, which already includes this component's source code, and the AI reproduces this exact effect instead of improvising.
Questions about Ábaco
Which formulas does Ábaco understand?
Ábaco uses the Brazilian Portuguese function names: SOMA for sum, MÉDIA for average, SE for if and PROCV for vertical lookup, plus MÍN, MÁX, CONT, ABS and ARRED. It accepts A1 references, ranges and absolute addresses with dollar signs. Arguments are separated by semicolons and decimals use a comma, as in Portuguese Excel.
Can Ábaco handle a lot of rows?
Ábaco works with 5 to 200 rows and 3 to 26 columns and draws every cell on screen, which is why THM Componentes rates it Heavy. For lists with thousands of records, Balancete, which is virtualized, is a better fit; the spreadsheet shines in budgets and simulators of a controlled size.
Does Ábaco work with a keyboard and on phones?
With a keyboard, fully: in Ábaco the arrows move, Shift extends the selection, Enter or F2 edits, Delete clears and Ctrl+Z undoes. On phones, a tap selects a cell and the formula bar accepts typing, but dragging a finger scrolls the grid instead of selecting a range.
