What is siei?

SIE (Swedish Import and Export format) is a standardized file format used in Sweden for transferring accounting data between different systems. It's primarily utilized by businesses and accounting firms to facilitate the exchange of financial information. The format is designed to be easily readable by both humans and computers, making data migration and analysis more efficient. SIE files can contain various types of accounting data, including chart of accounts, transactions, balances, and budget data. The different types of data are separated into different series within the file. SIE files are plain text files, and different versions of the standard exist, each with slight variations in the data they support. Using the SIE format helps ensure data integrity and simplifies the process of switching accounting software or sharing information with auditors and other stakeholders.
