As I understand, accepted answer will get you results w/out headers. You can use right-click on results -> export there use clipboard as save-as, format -> delimited and the trick — delimiter to TAB (at least with tab paste works properly for my Excel version, default comma does not).

It’s simple, select all the records from the output query result and copied it by using Ctrl+C then after open new DataBase File on top left side of the Oracle SQL developer. Then after paste all the data there into that DataBase File. Again copied the data from that DataBase files using Ctrl+C & paste it into the Excel Sheet.

I have a small project where data from Oracle SQL Developer needs to be exported to Excel (using commands rather than tools in SLQ Developer), then create a graph.
Using «spool» I can export to csv fine (but cant make a graph in csv) but when I try to export to xlsx it corrupts the whole excel sheet saying
"Excel cannot open the file "ExcelFile.xlsx" because the file format or file extention
is not valid. Verify that the file has not been corrupted and that the
file extension mathces the format of the file."
Here is the code I used in SQL Developer.
spool FileLocationExcelFile.xlsm
SELECT * FROM Table;
spool off;
Is there any way I can stop the data from becoming corrupted or is there another way to export data to a .xlsx file?

Nooooooo.
set sqlformat csv
spool c:file.sql
select * from table;
spool off;
then open the file in excel.
OR
Run your query interactively.
Right click on the grid, Export > XLSX. Open the file.
Spool only writes the query output to the file, it doesn’t look at the file extension and figure out HOW to write the output at that point.
So you either have to code it yourself via the query, or use one of the format outputs we support
SET SQLFORMAT
CSV
JSON
DELIMITED
XML
HTML
INSERT
LOADER
Use ‘help set sqlformat’ for help.

Hi sql developer from what I know for exporting is using sqlplus(code is same) so perhabs there are other ways but this one should be good enough
I would try changing first line to look like this:
spool ExcelFile.xls
Probably you also need to turn on
SET MARKUP HTML ON
http://www.orahow.com/2015/09/spool-sqlplus-output-to-excel-format.html
Anyway there is workaround — you can just generate .CSV file and then open it in excel and save as .xlsx file

I was also facing the same problem then applied below code and it exported successfully..
import xlsxwriter
from xlsxwriter import Workbook
import cx_Oracle
import datetime
from datetime import date
dsn_tns = cx_Oracle.makedsn('HOST', 'PORTNO', sid='BGRDB')
db = cx_Oracle.connect(user=r'username', password='password', dsn=dsn_tns)
cursor = db.cursor()
workbook = xlsxwriter.Workbook('C:/Path/outfile.xlsx')
sheet = workbook.add_worksheet()
cursor.execute("select * from TABLENAME")
for r, row in enumerate(cursor.fetchall()):
for c, col in enumerate(row):
sheet.write(r, c, col)
workbook.close()
cursor.close()

The export function for query result is not so obvious for developers to find out. In this post, I will show how to export query result as a Excel file.
Show Query Result as Grid
To show the query result in a grid table, you have to use F9 or Ctrl+Enter to format query result in grid.
SQL Developer Query Result
Right Click Mouse and Export
Move your cursor over anywhere on the grid and right click the mouse, you will see Export option.
SQL Developer Query Result — Export
Export Entire Table
If the data you want to export is a table, not a query result, you can directly right-click on the table and select Export in the menu.
SQL Developer — Table Menu — Export
Select Export Format
SQL Developer showed Export Wizard window for interaction. Although there’re many export types for us to select, we chose Excel format in this case.
SQL Developer Query Result — Export Format — Excel (.xls)
Select Text Encoding
I chose UTF-8 in order to match the database encoding.
SQL Developer Query Result — Export Encoding — UTF-8
Customize Filename
If you want to change the path, you can click Browse to navigate and choose a right directory to place.
SQL Developer Query Result — Export File Name — Browse

- Exporting Data
SQL Developer provides the ability to export user data to a variety of formats: CSV, XML, LOADER, TEXT, INSERT, HTML and XLS.
- In order to export the data from a table you can either use the SQL Worksheet and write a SQL query to retrieve the required data or you can Click on the Data tab of a table definition. We’ll use this latter approach.
- Right-click anywhere on the data to invoke the context menu.
- Choose an appropriate directory and name for the file.
- Click Apply to create the file.
- To review the file created, click the Open Folder icon
. Select the new file DEPARTMENTS.sql from your file directory. The sql file will open into a SQL Worksheet.
Expand the Connections Navigator and the Tables node.
Click on DEPARTMENTS.
Select the Data tab.
Select insert from the Export Data context menu. This will produce a file of insert statements.
You can also fine tune what is exported by selecting the columns and adding a where clause to reduce the number of records returned. In this example, we’ll take the default of all the records and columns.
- Exporting Object Definitions
SQL Developer provides the ability to export some or all of your object definitions to script files. You can use these as a backup of the object definitions or run them in another schema. In this exercise, you export all the object definitions and the data for the Departments table.
- Using the main menu, select Tools->Database Export.
- An Export wizard will open. At the top of the screen, enter a directory and file name. e.g. C:WorkingexportDept.sql. and select the Connection.

- In this step, you can slect what Object Types to export. We will take the default for all object types.
Click Next.
- In this step, you can specify the objects to export. Instead of querying all objects by immediately selecting Go, you can enter a restriction criteria. Enter D% and then click Go.
- You can restrict the list of choices further by using the drop list on the right.. Select Table from the list of object types.
- Select the table Departments and shuttle to the right hand panel.
- In this step, you can specify the data that gets exported. Click Go and a list of tables will be listed. Shuttle Departments to the right hand panel..
- In this final step, you can review your Export Summary.

Tutorial: Exporting Query Results
This is a 101 level type of topic – a fundamental bit of SQL Developer that I would encourage everyone to be familiar with. Why? Because it’s probably something you’ll be doing, A LOT. So let’s get into it, already!
You have two options for getting data from a query into a FILE.
- right-clicking on a result grid
- spooling to a file
Grid Exports
The ubiquitous data grid!
Spooling
Exporting Data from a Grid
Here’s what happens.
You’re executing a query, browsing a TABLE, or running a report.
You right-click on it.
What happens next?
You get a 2 screen wizard. The first screen looks like this:
Here comes trick #1
Trick #1: You’re going to be doing this, A LOT. So, go into preferences and setup your defaults. You can see by my screenshot that I’m most frequently doing CSV exports directly to my clipboard.
Once you’ve set what you want, and click NEXT, you review what you’ve asked for and say FINISH.
But then what happens?
WE EXECUTE THE QUERY AGAIN. Grab the results, format them based Wizard settings, and feed them to the destination you’ve selected.
Trick #3: If you’re dealing with a large amount of records and are exporting to Excel, always choose the XLSX format (we list it first). If you choose XLS instead, stubbornly, it’s going to peter out after a hundred thousand rows or so…if you do not see the XLSX format option, that means YOU NEED TO UPGRADE SQL DEVELOPER.
Trick #4: If you have BLOBs in your query resultset, the ONLY way to export those out successfully is to use the Loader format option.
Exporting Data from a Script
Once you’ve ran the script and are looking at the results, the only way to get those into a file is to copy/paste.
So, what you need to do is tinker with your script, and have it use the SPOOL command.
SPOOL is a SQL*Plus feature that we support in SQL Developer. You have access to this command and other script processing bits when you use THIS button (or F5) to execute something.
This one!
We do better than just support the SPOOL command. We have built some additional commands to make working with FILES much easier.
Let’s look at this ‘script’:
The ‘cool’ parts of this script are:
And that’s it. Well, that’s ALMOST it. If you have a VERY LARGE result-set, writing those query results to the screen AND to the file at the same time is going to be a major BUMMER.
And now you know, the rest of the story.

Hi Jeff, when exporting to .xlsx or .csv is it possible to change the font the data is exported in?
I doubt we assign a font to a csv file…
Do you mean file encoding?
Hope you are well. I have been trying to export the result of a query. However I seem to get the following stack trace:

The actual query that I am trying to run is about 660KB in size. I tried to reproduce the issue with the different query – shown below. The version of SQL developer is v18.4 . I was able to reproduce on v20.2 as well.
select sysdate, case when (1 = 2 or 1 = 2 or …. 1 = 2) THEN ‘EQUAL’ ELSE ‘NOT EQUAL’ end as CASE_VALUE from dual;
Around the time this SQL query reaches 8260-8280 bytes in size. The export from SQL developer fails with the above stack trace.
Just in case, please go try version 20.4, it has lots of bug fixes over 20.2.
