I have written a code to convert a Word document into an excel sheet.
The problem is that whenever there is a point starting with bullets in Word document line after a colon, after getting converted into excel sheet it is appearing into different cells or say column.
I want everything into the same cell but it is creating extra cells.
I want a code to handle this problem.
suppose if the line is:
I have three cars:
all belong to the same brand
.car1
.car2
.car3
in excel sheet the data is comming like
i have three cars,all belongs to same brand,car1,car2,car3
take commas as cells, but I want each data to be in the same cell.

I'm trying to shift rows down in my excel sheet and insert new data to the top of the list.
I'm able to shift rows down as:
int row = getItemsListSize(); <- which returns size of the list which contains elements
sheet.shiftRows(1, sheet.getLastRowNum(), rows);
Then I insert new data starting from row 1 and that way newest data is always on top of the list and older data gets moved down.
My problem is that I have second table also on that sheet and amount of items inside it isn't same as in first table. Currently also contents of this table gets moved down although no new items aren't added. Because of that it looks weird.
Is there way to only shift rows inside specific columns? For example: Move rows only in columns A-D.
No; from an excel perspective, there is no such thing as two separate tables. It's just one big sheet with rows and columns. Apache POI is a library that gives you access to excel's data structures. It's not a generalized 'mess with sheets' library. You'd have to write the code for such such a thing yourself.
More generally you're misusing excel a bit. The right move usually is to treat data, as, well, data. You should not be having 2 unrelated tables on the same sheet. Use the + button at the bottom left (or the appropriate POI option, which also supports sheets) to add another sheet.
If you want a sheet for visual reasons, make a third sheet, and that is a sheet that your POI code should never touch - it will render the data from the other (data) sheets. You can now add graphs, logos, whatever you want, and you won't run into issues where moving things around a bit 'because it looks nicer visually' then results in your POI-based code being broken.
I created a report with JXLS and an excel template. I have a bunch of cells/columns pulling data from my database, then I have a few columns that are blank, and then I have some formulas/conditionals in a few columns in my report as well. The issue I am having is that one of the formulas, needs to run/ multiply two blank columns (someone will download the report and input the numbers manually in those blank columns), and when I run the generate the report through my Java app, the column with the formula comes up as =0. Anyways to get the formula to stick, so the people manually entering the numbers in the blank columns do not have to add/input the formula themselves?
You should get Jxls to process AC and AD cells by putting a dummy JEXL expression in there.
The simplest way is to put ${null} into AC and AD cells in your template.
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 have an Excel template with first 5 columns left blank (to be populated from an XML). The sixth column has a drop-down list such that depending on whatever value is selected from the list, a value appears in 7th column. This is done by using INDEX-MATCH formula for the 7th column.
=INDEX(Sheet7!$B$1:$B$312,MATCH(F3,Sheet7!$A$1:$A$312,0))
The task is to take this template Excel, and using POI, populate the first 5 columns and generate a new Excel workbook. (Not changing in the existing sheet).
The problem is when I generate the new Excel workbook, the formula isn't copied over from the template. It is really important to retain the formula for the task I am working on. I read about
formulaEvaluator()
but I don't think it'll work in that case because I need the formula to be retained as it is. I cannot evaluate it before copying as there won't be any data in column 6 at that point to evaluate the formula and store the value.
I'd really appreciate if someone who has any experience in this area could guide me a bit.
If you have access to the Cell, simply call:
String formula = cell.getCellFormula();
Note though that this will only work if the cell is formula cell. IE: cell.getCellType() == Cell.CELL_TYPE_FORMULA. If the cell is not a formula cell, you're going to end up with an IllegalStateException as described in the API
I populated Excel worksheet using HSSFWorkbook. I am facing a problem in formatting a cell. I have two colummns with contain varying text sizes. If the row in Column B is not empty then the text from Column A does not overlap that in Column B. However, If Column B is empty, the text in a row of column A appears to be continuing onto Column B which is not desired.
Can someone please help me how I can avoid text in Row 1 Column A not to continue onto Row 1 Column B? I do not want to use wrap because that would make the height of Row 1 inconsistent with the other rows. Also, I do not want to adjust the width of Row 1 to match the text size because that is not desired.
Thanks,
H
Described behavior
If Column B is empty, the text in a row of column A appears to be continuing onto Column B
is a standard Excel behavior and has nothing to do with POI. So try first avoiding it in the Excel itself (putting a space in B column as trashgod advices would do) and than reproduce it using POI.
