[Scala]Excelシートに入力する式を生成する

Posted at

Excelシートに入力する式は、IF文などを使い始めるとだらだらと長くなる。
よって、Scala等で構成してしまって、貼り付けるだけにする。

def expression(cells:List[String], rows:Int) = {

  val ors = cells.map(c => c + rows + "=\"?\"," + c + rows + "=\"\"").mkString(",")

  val corrects = cells.map(c => c + "$1").mkString(",")

  val answers = cells.map(c => c + rows).mkString(",")

  "IF(OR(" + ors + "),\"?\",IF(AscStr" + cells.size + "(" + answers + ")=AscStr" + cells.size + "(" + corrects + "),\"o\",\"x\"))"

}
