From this topic.
Sample window attached. The script in the button will export multiple tables and put them in separate sheets.
You may either download it from there or from here. Your choice! 
EDIT: renamed topic to something making more sense… 
Export Multiple Table to Excel_2014-10-27_0935.proj (20.6 KB)
This link you provided is not working.
This is close to what I am looking for and was hoping to look at the project to help figure out what I needed. Can you possibly fix the download link?
Rats! I hate it when the forum drops my stuff.
Actually, it’s not needed anymore, since system.dataset.dataSetToExcel() has it built in (as of 7.9.8). You will need to make a list out of the datasets you use:
# get datasets
dataIn_1 = event.source.parent.getComponent('Table 1').data
dataIn_2 = event.source.parent.getComponent('Table 2').data
# create spreadsheet
spreadsheet = system.dataset.dataSetToExcel(1, [dataIn_1, dataIn_2])
# set file path to save the spreadsheet
filepath = 'c:/path/to/save/results.xls'
# write the file
system.file.writeFile(filepath, spreadsheet)
Hi,
I Have Same Doubts In Perspective. How should i do this in perspective. i’ve multiple tables i want to export this tables one after another in a single excel sheet.
i using this Code…
data_1 = self.parent.getChild("FlexContainer").getChild("Table").props.data
data_2 = self.parent.getChild("FlexContainer").getChild("Table_0").props.data
fileName = 'Example File'
data_tab = [data_1,data_2]
datasetData = []
for tabName in data_tab:
data = tabName
headers = data[0].keys()
#system.perspective.print(data)
for row in range(len(data)):
rowData = []
for col in range(len(headers)):
cell = data[row][headers[col]]
if hasattr(cell, 'value'):
rowData.append(cell.value)
system.perspective.print(headers)
else:
rowData.append(cell)
#system.perspective.print(rowData)
datasetData.append(rowData)
finalDataset = system.dataset.toDataSet(headers,datasetData)
excelFileName = str(fileName) + ".xlsx"
excelBytes = system.dataset.toExcel(True,[finalDataset]) #returns .xls file as bytes
system.perspective.download(excelFileName, excelBytes)
i not get my desired output…
How should i need to modify this code…
i want…
each table print one after another with some space(One Column)…
i am new in this environment…
Thanks For Advance 
Hi @JordanCClark ,
I have created excel with 2 spreadsheet as you mentioned.Now the Spreadsheets names are (dataset,dateset1). But I need to Change that spreadsheet names.
I tried this one ,
sheetNames = ["Production", "Downtime"]
excelData = system.dataset.exportExcel(1,[Dataset, Dataset1], sheetNames)
But it is not working.
Any One Have A Idea Please Provide.
Thanks in advance!.
Not sure where the idea came from, but exportExcel() is not documented to accept sheet names.
Here is a modified version of a function I wrote in this thread:
def listToExcel(datasetList, fileName = '', sheetNames = 'Sheet {}', dateFormat = 'yyyy-mm-dd hh:mm:ss'):
''' Convert a list of datasets to Excel
params:
datasetList: The list of datasets to convert. Valid types are:
- com.inductiveautomation.ignition.common.BasicDataset
- com.inductiveautomation.ignition.common.script.builtin.DatasetUtilities$PyDataSet
- com.inductiveautomation.ignition.common.JsonDataset
fileName: The name to save the Excel file. If omitted, the output will be a byte array.
This is useful to use with perspective (e.g. system.perspective.download)
sheetNames: List of names The tab name of the workbook. Default is Sheet 1, Sheet 2, etc.
dateFormat: How dates should be formatted, e.g. 'yyyy-mm-dd hh:mm:ss'.
Note that Excel does not use capital letters, because... Microsoft.
The script will auto lower-case your format.

Hi @JordanCClark ,
I Found that idea from Chat GPT.
thanks for Your Quick response.
But , I need this in perspective.i am using > system.perspective.download(filename, data)
this is my script:
ds = system.db.runNamedQuery("My_named_Query",parameters)
ds1 = system.db.runNamedQuery("My_named_Query1",parameters)
data = system.dataset.toExcel(True,[ds,ds1])
filename = 'Data.xlsx'
system.perspective.download(filename, data)
With no filename in the function I supplied, it returns a byte array.
ds = system.db.runNamedQuery("My_named_Query",parameters)
ds1 = system.db.runNamedQuery("My_named_Query1",parameters)
data = util.dataset.listToExcel([ds, ds1], sheetNames = ["Production", "Downtime"])
filename = 'Data.xlsx'
system.perspective.download(filename, data)
i need to import any library?
because I got this error:
NameError: global name 'util' is not defined
Copy. Paste into a project script of your choosing. Set your path to the function accordingly.
Without seeing any data, I would say that the times are coming in as milliseconds and not a date
exportExcel doesn't, but toExcel does:
https://docs.inductiveautomation.com/display/DOC81/system.dataset.toExcel
Easy enough to pair with system.file.saveFile if you wanted.
Yes.
the times are coming in as milliseconds .
I Changed to Date. now it is working !..
Thanks @JordanCClark for Your Quick responses.
Have a great day 
...
Thanks @PGriffith
This one also working. I think it is very simple and easy way.
This is the code:
ds = system.db.runNamedQuery("My_named_Query",parameters)
ds1 = system.db.runNamedQuery("My_named_Query1",parameters)
data = system.dataset.toExcel(1,[ds, ds1], sheetNames = ["sheetName1", "sheetName2"])
filename = 'Data.xlsx'
system.perspective.download(filename, data)
Thank again
