Microsoft researchers have recently unveiled an innovative research called SpreadsheetLLM, aimed at addressing the challenges faced by large language models (LLMs) when parsing electronic spreadsheets.
According to a paper published on Arxiv on July 12th, SpreadsheetLLM enables LLMs to "read" spreadsheet content through an encoding framework. This research is expected to significantly enhance the efficiency of data management and analysis in spreadsheets, allowing users to ask questions of AI in natural language without needing to master complex formulas and operations.

Spreadsheets pose multifaceted challenges to LLMs. Firstly, spreadsheets can be extremely large, exceeding the character limit that LLMs can process at once. Secondly, spreadsheets use a two-dimensional layout and structure, whereas LLMs are adept at handling linear, sequential inputs. Lastly, LLMs are typically not specifically trained to interpret cell addresses and specific spreadsheet formats.
Microsoft's SpreadsheetLLM technology consists of two main components. The first is SheetCompressor, which reduces the complexity of spreadsheets to make them more understandable to LLMs. SheetCompressor includes three modules: structural anchors, methods to reduce the number of tokens, and clustering similar cells to improve efficiency. Using these modules, the Microsoft team reduced the number of tokens required for encoding by 96% and achieved a 12.3% improvement in effectiveness. The second component is the Chain of Spreadsheet, which teaches LLMs how to find relevant information and generate responses within compressed spreadsheets.
The successful application of this technology will significantly enhance the capabilities of Microsoft's Copilot in Excel, enabling it to handle more complex data analysis tasks. However, this method still faces issues with the accuracy of generated data and high computational resource consumption. Future plans for the research team include encoding cell background colors and deepening the understanding of the relevance of cell content.
Key Takeaways:
📊 **Challenges for Large Language Models (LLMs) in Spreadsheets**: Spreadsheet structures are complex and use a two-dimensional layout, which goes beyond the linear input range typically handled by LLMs.
🔍 **SpreadsheetLLM Technology Analysis**: Microsoft has introduced two core technologies, SheetCompressor and Chain of Spreadsheet, which greatly enhance the ability of LLMs to understand spreadsheets.
🛠️ **Impact on Microsoft's AI Tools**: SpreadsheetLLM is expected to strengthen the capabilities of Microsoft's Copilot in Excel, but currently faces challenges with the accuracy of generated data and computational resource consumption.
