Towards unifying spreadsheets with databases for ad-hoc interactive data management at scale
… interface. DataSpread holistically unifies spreadsheets and relational databases to leverage the benefits of both. However, this holistic integration is not trivial due to the differences in the architecture and ideologies of the two paradigms: spreadsheets and databases. We have built a …

Layout Inference and Table Detection in Spreadsheet Documents
Spreadsheets have found wide use in many different domains and settings. They provide a broad range of both basic and advanced functionalities. In this way, they can support data collection, transformation, analysis, and reporting. Nevertheless, at the same time spreadsheets maintain a friendly and …

Towards a Theory of Spreadsheet Accuracy: An Empirical Study
Electronic spreadsheets have made a major contribution to financial analysis and problem solving. Although professionals base many decisions on the analysis of a spreadsheet model, literature documents the data quality problems that often occur, i.e. underlying formulas and resulting numbers are …

An extended spreadsheet paradigm for data visualisation systems, and its implementation
… describe a data visualisation system which uses spreadsheets as its user interface metaphor. Similar systems implemented in the past were hampered by the contradiction between an imperative formula language and the declarative spreadsheet framework. We have analysed spreadsheets from a data …

Refactoring meets spreadsheet formulas
… software. We studied a corpus of 3691 spreadsheets and we found that their formulas are riddled with the same smells that plague professional software: hardcoded constants, duplicated expressions, unnecessary complex- ity, and unsanitized input. These make spreadsheets difficult to read …

A spreadsheet-based user interface for managing plural relationships in structured data
… at hand, information workers instead turn to spreadsheets, a general and more familiar data management tool which, unfortunately, lends itself poorly to schemas requiring multiple related entity sets. In this thesis, we propose to reduce the cost-usability gap between spreadsheets and …
