As AI continues to reshape every corner of the digital landscape, Microsoft is now turning its attention to a critical yet often overlooked domain of office work: the spreadsheet.
The tech giant has introduced an experimental AI model called SpreadsheetLLM to enhance the functionality of spreadsheets. The new model, detailed in a research paper by Microsoft, aims to solve the challenge of harnessing the power of AI with the structured data found in spreadsheets.
While the Microsoft researchers emphasized the importance of spreadsheets in business, they also highlighted their limitations. Traditional spreadsheets struggle to understand and reason over the contents of spreadsheets.
The SpreadsheetLLM is developed to encode spreadsheet data in a more LLM-friendly way. The initial method used by the researchers relied on using spreadsheet cell addresses, values, and formats, but they found this method was limited by the LLM token constraints, making the method impractical for most applications.
Large language models (LLMs) are trained on standard linear tokenization techniques, and they struggle when working with the infinite cell-like nature and reference to cells in spreadsheets.
To overcome these challanges, the researchers developed a novel mechanism, called SheetCompressor, that encodes spreadsheet contents into a new format that is more compatible with LLMs. This innovative encoding framework compresses spreadsheets making them more accessible for LLMs. It analyzes spreadsheet structure, translates data into more efficient representation, and then aggregates the data.
The researchers claim that they comprehensively evaluated the new method to find that it can compress data by up to 96%, allowing LLMs to handle large datasets within their token limits. The model performed exceptionally in spreadsheet table detection, outperforming existing methods by 12.3%.
The use of AI to boost spreadsheet performance and efficiency is not new. Microsoft Excel Ideas feature uses AI to suggest visualizations, charts, and pivot tables based on selected data ranges, making it easier for users to identify trends and patterns. Google Sheets’ Smart Fill feature uses AI to detect patterns in data and automatically suggest completions.
Several other companies are integrating AI to advance the functionality of spreadsheets. Some startups, such as Airttable and Rows, are even offering AI-native spreadsheet alternatives. However, Microsoft Excel remains the industry standard for many users.

The Microsoft researchers tested SpreadsheetLLM with some of the most popular LLM models including the GPT-4, Llama 3, and Phi-3, and Mistral-v2. The results were impressive with GPT-4 showing 27% performance improvement in its ability on spreadsheet understanding tasks compared to previous methods.
SpreadsheetLLM is still an experimental model, and the researchers admit that it has some limitations, especially when working with complex spreadsheet formats. However, they believe SpreadsheetLLM has great potential in AI-driven data analysis and decision-making. It also has the potential to free users from tedious tasks such as data entry, formatting, and aggregation.
With its flexible layout and varied formatting options, spreadsheets have been a staple for many businesses and jobs. The introduction of SpreadsheetLLM can also help democratize the use of spreadsheets by making them easier to use for everyone and potentially transforming the future of work. Using natural language processing, users can query and manipulate data with plain English instead of complex formulas or programming languages.
Looking ahead, the researchers plan on exploring advanced semantic compression techniques to enhance the capabilities of SpreadsheetLLM. Microsoft‘s research paper may have laid the foundation for SpreadsheetLLM to evolve into a powerful copilot for Excel in the future.
