Cannot import XSSF in Apache POI

Question

I am referencing the version 3 7 of the Apache POI and I am getting a  cannot be resolved  error when I do   import org apache poi xssf usermodel XSSFWorkbook    Other import statements that reference POI DO NOT give me errors  such as   import org apache poi ss usermodel      Any ideas

After trying multiple things what really worked was  1  downloading  poi  and  poi-ooxml  manually 2 Adding these d w jars into  Maven Dependencies

I had the same problem  so I dug through the poi-3 17 jar file and there was no xssf package inside   I then went through the other files and found xssf int the poi-ooxml-3 17 jar  So it seems the solutions is to add  poi-ooxml-3 17 jar   to your project  as that seems to make it work  for me at least

I Got the Solution Guys You need to keep some points in your mind    There are two different dependency one is  poi   amp  other dependency is  poi- ooxml  but make sure you must use poi-ooxml dependency in your code   Just Add the following dependency in pom xml  amp  Save it     lt dependency gt     lt groupId gt org apache poi lt  groupId gt     lt artifactId gt poi-ooxml lt  artifactId gt     lt version gt 3 9 lt  version gt     lt  dependency gt   3  After you have saved the pom xml then you need to try a small thing  Use     operator will try to import fetch it  amp  finally will not see any sort of error because now it has imported that thing in your package  Sample Code to Understand Better    package ReadFile    package    import org apache poi xssf usermodel XSSFWorkbook      automatically added to your code after importing public class Test               public static void Hello      Method       XSSFWorkbook workbook   new XSSFWorkbook              I tried my best to give you the solution   If you face any issue comment here i will try to solve it   Keep Learning Guys

For OOXML to work you need the POI-OOXML jar which is separately packaged from the POI jar   Download the POI-OOXML jar from the following location -  http   repo1 maven org maven2 org apache poi poi-ooxml 3 11 poi-ooxml-3 11 jar  For Maven2 add the below dependency -   lt dependency gt       lt groupId gt org apache poi lt  groupId gt       lt artifactId gt poi-ooxml lt  artifactId gt       lt version gt 3 11 lt  version gt   lt  dependency gt

You did not described the environment  anyway  you should download apache poi libraries  If you are using eclipse   right click on your root project   so properties and in java build path add external jar and import in your project those libraries     xmlbeans-2 6 0   poi-ooxml-schemas-       poi-ooxml-       poi-

The classes for the OOXML file formats  such as XSSF for  xlsx  are in a different Jar file  You need to include the poi-ooxml jar in your project  along with the dependencies for it  You can get a list of all the components and their dependencies on the POI website here   What you probably want to do is download the 3 11 binary package  grab the poi-ooxml jar from it  and the dependencies in the ooxml-lib directory  Import these into your project and you ll be sorted    Alternately  if you use Maven  you can see here for the list of the artificats you ll want to depend on  but it d want to be something like    lt dependency gt      lt groupId gt org apache poi lt  groupId gt      lt artifactId gt poi-ooxml lt  artifactId gt      lt version gt 3 11 lt  version gt   lt  dependency gt    The poi-ooxml maven dependency will pull in the main POI jar and the dependencies for you automatically  If you want to work with the non-spreadsheet formats  you d also want to depend on the poi-scratchpad artifact too  as detailed on the POI components page

I needed the following files for my implementation    poi-ooxml-schemas-3 14 20160307 jar commons-codec-1 10 jar  this was in  lib  folder of the zip file you get from apache  curvesapi-1 03 jar  in  ooxml-lib  folder  poi-3 14-20160307 jar poi-ooxml-3 14-20160307 jar xmlbeans-2 6 0 jar  in  ooxml-lib  folder     though honestly  I m not completely sure they are all necessary      It s a little confusing because they are packaged that way   I needed to place them manually in my own  lib  folder and then add the references     Maven always seems to download more than I need  so I always place libaries dlls and things like that manually
