A BOQ can arrive in several different file formats depending on who prepared it, and not every format opens the same way. Here’s what each common BOQ file type needs to open correctly, and which one you should actually be using.
Common BOQ File Formats and What Opens Them
| File Format | Opens With | Editable? |
|---|---|---|
| .xlsx / .xls | MS Excel, Google Sheets, LibreOffice Calc | Yes — fully editable, formulas intact |
| Any PDF reader (Acrobat, browser, Preview) | No — view/print only, needs conversion to edit | |
| .csv | Excel, Google Sheets, any text editor | Yes, but loses formulas/formatting |
| .dwg (BOQ tagged to drawing) | AutoCAD, DWG TrueView (free) | Requires CAD software |
| Estimating software exports (.est, proprietary) | The originating software, or export to Excel/PDF | Only in that software, unless exported |
If Your BOQ File Won’t Open
- Check the file extension — a mislabeled extension (e.g., a .xls file renamed .xlsx) can cause “corrupted file” errors; try opening in Excel directly and letting it repair.
- Try Google Sheets — free, browser-based, and opens most .xlsx/.xls/.csv files even without Excel installed.
- Ask for a PDF export — if you only need to view the BOQ, a PDF is universally viewable without any special software.
- Convert with LibreOffice Calc — free desktop software that opens and can re-save most spreadsheet formats.
