The ecoSpold1 format was used in ecoinvent version 2 and was superseded by ecoSpold2. 

Oct 26th, 2023

The ecoSpold1 Data Exchange Format 

It is based on XML (extended markup Language) and related technologies (XSL, XSLT, Schema). 

The data format was developed as part of the ecoinvent projects. The ecoSpold1 format was used in ecoinvent version 2 internal applications as well. The administration tool, the editor tool and the server tool used this format for the exchange of data, both amongst each other as well as with other applications. 

The online platform of the ecoinvent version 2 database and ecoSpoldAccess both support and use ecoSpold1. 

 The data exchange format lists all data fields available for the documentation of a single data set (LCI raw data and meta information of a unit process) and specifies the expected content. 

It takes pattern from the international SPOLD 99 data exchange format and has been adapted to the ISO Technical Specification ISO 14048.

Features of the ecoSpold1 Access Macros 

The ecoSpoldAccess macro allows you to open ecoSpold1 files in Microsoft Excel, edit them in a limited way and to export them back from Microsoft Excel format to the ecoSpold1 format. The ecoSpoldAccess add-in was developed for Windows XP and Excel 97. 

However, due to the migration to ecoSpold2, the ecoSpoldAccess add-in is no longer maintained and is not compatible with more recent versions of Microsoft Excel. 

Please note that the conversion from Microsoft Excel to ecoSpold1 of results files may take some time (around 10 to 20 minutes) depending on the Excel version used and its settings. If you encounter problems and you would need the Microsoft Excel files for LCA calculations, please contact us.

If you just want to look at the files, please visit the ecoinvent version 2 database then simply login to the online platform of the database.
