Spreadsheets are flexible workbooks for organizing data, running calculations, and building custom reports. Use them to track material costs, estimate labor, summarize bids, or structure any data your project requires.

To create a new spreadsheet, open the Spreadsheets section of your project and click the spreadsheet name dropdown in the toolbar. Select New spreadsheet at the bottom of the list, enter a name, and click Create. The spreadsheet opens immediately in the editor.

You can switch between spreadsheets at any time using the same dropdown. A checkmark indicates which spreadsheet is currently open.

The editor works like any modern spreadsheet application. Click a cell to select it, then start typing. Press Enter to confirm and move down, or Tab to confirm and move right. Double-click a cell to edit its contents in place.

Formulas start with an equals sign. Use =SUM(A1:A10) to total a range, =AVERAGE(B1:B20) for means, or =IF(A1>100, "Over", "Under") for conditional logic. Cell references update automatically when you move or copy cells.

Select cells and use the built-in formatting toolbar to apply bold, italic, text colors, background colors, borders, and number formatting. You can align content left, center, or right, and format values as currency, percentages, or dates.

Each spreadsheet can contain multiple sheets. Add a new sheet by clicking the + tab at the bottom of the editor. Right-click any sheet tab to rename, duplicate, delete, or reorder it. Drag tabs left or right to change their order.

To rename or delete a spreadsheet, use the spreadsheet dropdown in the toolbar. The dropdown lists all spreadsheets in the project, and each entry provides options for managing that spreadsheet.

Click Import in the toolbar to bring in data from .xlsx, .csv, or .txt files. The import dialog lets you choose where to place the data: create a new spreadsheet, add a new sheet, replace the current spreadsheet or sheet, or append to the current sheet. CSV imports support auto-detected or manual separator selection.

To export, click Download and choose Excel (.xlsx), CSV (.csv), or PDF (.pdf). The PDF option opens a print preview where you can configure page setup, scale, headers and footers, and which sheets to include.

Press Cmd+P (or Ctrl+P on Windows) to open the print dialog, or click Print in the toolbar. The print preview shows page thumbnails on the left, a full-size preview in the center, and configuration options on the right. You can adjust paper size, orientation, margins, scale, and whether to repeat frozen rows and columns on each page.

Changes save automatically as you work. A Saving... indicator appears briefly in the toolbar while your edits sync. If it persists, check your internet connection. Unsaved changes will sync once connectivity returns.
