This volume contains the papers presented at SEMS'15: Second Workshop on Software Engineering Methods in Spreadsheets held on May 18, 2015 in Florence, Italy, as part of the 37th International Conference on Software Engineering (ICSE). The workshop was organised by Felienne Hermans (TU Delft), Richard Paige (University of York) and Peter Sestoft (IT University of Copenhagen) as a result of their observations that signi cant research was taking place on spreadsheets in software engineering, and that the time was ripe for a collective meeting bringing together people from di erent communities - e.g., the end-user programming community, modelling community, testing and veri cation community, etc. A rst workshop had been organised in 2014, co-located with Eusprig, in Delft, the Netherlands. The program committee reviewed and selected 11 papers (including short papers, long papers and tools papers) for presentation during the workshop. Each paper received 3 reviews, and there was further discussion amongst the reviewers and organisers to select these papers from amongst 16 submissions. The organisers would like to thank the ICSE'15 local organising team for their support for organising the workshop as part of ICSE; the workshop chairs were particularly helpful in coordination. As well, they would like to acknowledge use of Easychair in organising the program committee activities. Normally, ICSE workshop proceedings are published behind a paywall, in the ACM or IEEE Digital Library. The organisers of SEMS support full open access publication of all publically funded research, and are pleased that it was possible and feasible to publish the proceedings in CEUR.
