Sheet
statement
Sheet is a Scala DSL to read and write Excel spread sheets, based on Apache POI.
Note: This is a fork from George Leontiev (folone)'s original project poi-scala. What I did here is remove the Scalaz dependency, and publish an independent artifact.
building
Builds with sbt 0.13 against Scala 2.12, 2.11, 2.10. Run sbt test, or start using sbt console.
linking
"de.sciss" %% "sheet" % v
The current version v is "0.1.2".
Note: There is a stax-api dependency coming from Apache POI. If you experience name conflicts when using sbt-assembly in your project, apply this "simple" sbt code:
assemblyMergeStrategy in assembly := {
case PathList("javax", "xml", xs @ _*) => MergeStrategy.first
case x =>
val oldStrategy = (assemblyMergeStrategy in assembly).value
oldStrategy(x)
