Formats it accepts
Who it's for
BC3 is the standard exchange format for construction budgets in Spain — exported by Presto, Arquímedes, and TCQ — but it's a plain-text format of its own, not something Excel opens directly.
This converter reads the BC3 file with a parser built specifically for the FIEBDC-3 format and puts every line item into an Excel row: code, description, unit, price, quantity, and total. It all happens in your browser.
Upload the .bc3 file, check the preview of the line items, and download the full Excel file.
How to use it without losing traceability
The recommended workflow is simple: keep the original file, process a copy and check the preview before downloading it. The converter performs one specific transformation, but it does not decide whether the data is complete, the units are correct or the result fits the system where you plan to import it.
What to check before using the file
Open the result and review several rows at the beginning, middle and end. Check sheet names, headers, separators, special characters and quantities. For technical or financial documents, keep the original beside the converted copy so you can explain which version was used and repeat the process if a difference appears.
