I'm reading and evaluating an excel file with POI. I need to read the dropdowns from the file and display them as an HTML form element.
I can read the current value from the cell that contains a dropdown, but I can't get the list of all the other possible values.
As per this SO answer I tried using the DataValidations class to read the dropdown, but I think this is only for setting validations and not getting them. The DataValueConstraint.getExplicitListValues() method returned an empty list.
Does anyone know how to get the dropdown values? Can you show me some code that just prints the list of values?

I worte a code, that generated an output, where other people should choose an acknowledgment value 0,1 or 2. But some people ignored the "value rules" and they wrote other things into the cells. Now I want to generate the output with radio buttons and a textfield for comments. It should not be possible anymore to write other things into the ACKValue cells.
Is this possible to code with Java Apache? Can somebody give me some keyword how to do it. At the end it should be possible to read in the file again and sort the rows with respect to the chosen value.
Can anybody please let me know how to read the values of Excel form controls (radio button, checkbox, drop-down etc) in Java?
I tried using Apache POI, but I couldn't find a way to read the value of radio buttons or checkbox.
I know that I can link the form control with a particular cell in excel, and when the value of form control changes, read the data from that cell. But, instead of following this approach, I am looking for a way to directly read the value of form control.
I searched google but couldn't find anything useful. So can anybody please help me here?
I do not have any limitation of using any API's. So please let me know if this can be done in Java or not.
I have an Excel sheet with as 5 rows and 3 columns containing values.
What I need is :-
-To read the values row wise each time and input into corresponding 3 textboxes in a webpag e and click submit button
- Then page refreshes and then fetch the next row values in excel ,assign the values to the textfields perform the submit action
In a nutshell, how can we assign the values row wise enter image description here from an excel sheet to multiple textboxes in a page one after the other?
For read excel sheet and storing it into the variables in java probably the best way is to use Apache POI library .This library lets you manipulate excel documents and more. I found some example how to use Apache POI to read data from excel. After that you can you can store the cells inside the variables and use variables to insert the data into the website. Hope this gets you on the right track.

I am using Kettle for data migration for moving data, I come across a scenario where i got a excel where the column header is merged, When i read it only the first cell gets the name others are empty, Kettle can only duplicate values vertically, I have a macro which does the exact same thing, But some one has to do it manually, Is there a java code i could run to achieve this?
What do you mean by merged? In the excel file is there one cell with all the values? Is there a separator? If it's not a great deal of columns I'd just manually add them or change them to what I want using a select step. If you'd like to upload files I'll take a look.
I think, got the solution. Here Java code is not required. Please follow the step to achieve your result.
Step1: Drag and drop Microsoft Excel Input to the canvas.And go to Content uncheck Header.
Step2: Go to !Fields tab. See the below image and fill up like below image.
Step3:Go to Additional output fields tab and then check for sheet row nr field and fill up the check box with row_number.
Step4:Finally, click on preview button. You get the result like below.
If you see the result. First three rows are unnecessary. You can filter those three rows by using Filter step this part I'am not done.
i have an application where i read an excelfile(.xls), make some calculations and present the result. At the result is a button implemented which opens the original excelfile.
Is it possible to provide the specific cell as an arguement to show the cell directly, so that the user does not have to select the cell by himself?
The selected cell is stored within the Excel file. You have to study the API of your Excel writing library to find out, how to set this.
E.g. with POI it would be http://poi.apache.org/apidocs/org/apache/poi/xssf/usermodel/XSSFSheet.html#setActiveCell(java.lang.String)
Like Holger and Moritz said in their comments, it seems that that it is not possible to startup excel with a given cell preselected.
