Excel file getting corrupted while downloading using PowerShell/Curl

I am trying to download an Excel file from Artifactory to my local machine using a PowerShell/Curl script. The Excel file is getting created, but when I open a sheet I am getting the below message and there is no data in this.
The file format and extension of 'DataSheet_DEP.xls' don't match. The file could be corrupted or unsafe. Unless you trust its source, don't open it. Do you want to open it anyway?
curl.exe -k -u artifactory_TEMP:Password16 https://../artifactory/../DataSheet_DEP.xls --output D:\ABC\Team Members\Datasheet\DataSheet_DEP.xls
Just to add Excel file is in 97-2003 workbook (.xls). I am able to download the file manually without any issue.
This is resolved now.. I was using wrong artifactory path. Thanks everyone who tried to help here

SSIS Package strange data flow issue, spitting out empty excel with large dataset

I am having issue with the SSIS package, by Running from BIDS I could export 400K records successfully, But when I tried to run from the Job the package ran successfully but the excel file is empty.
The user which I am running the package with having the full access to the C:\Users folders. and I see it saving the data into the temporary folder but not writing that data into the file and finish with empty file.
For example : 230000 records (works good)
Create the excel file
Load the temporary data
Write data into the file
close the file
330000 records (not working)
Create the excel file
Load the temporary data
Write data into the file xxxxxxx this line missing from the process monitor
close the file
Solution : give permission to the user executing the package to the folder C:\Users\Default doesn't work for me.
Please help!
Sorry for bugging you guys, Found the problem. There was just 1.6GB of disk space on the server, thought the file is taking just 200MB of space but generate lots of temporary files causing the disk full error. Strange that SSIS package ran successfully without giving any warning or error. Thanks for looking into it.

What .xlsx file format is this?

Using an existing SSIS package, I was trying to import .xlsx files we received from a client. I received the error message:
External table is not in the expected format
These files will open in XL
When I use XL (currently XL2010) to Save As... the file without making any changes:
The new file imports just fine
The new file is 330% the size of the original file
When changing .xlsx to .zip and investigating the contents with WinZip:
The original file only has 4 .xml files and a _rels folder (with 2 .rels files):
The new file has the expected .xlsx contents:
Does anyone know what kind of file this could be?
It would be nice to develop my SSIS package to work with these original files, without having to open and re-save each file. There are only 12 files, so if there are no other options, opening/saving each file is not that big of deal...and I could automate it with VBA going forward.
Thanks for any help anyone can provide,
CTB
There are many Excel file formats.
The file you are trying to import may have another excel format but the extension is changed to .xlsx (it could be edited by someone else) , or it could be created with a different Excel version.
There is a Third-Part application called TridNet File Identifier which is an utility designed to identify file types from their binary signatures. you can use it to specify the real extension of the specified file.
Also after a simple search on External table is not in the expected format this error is thrown when the definition (or version) of the excel files supported in the connection string is different from the file selected. Check the connection string used in the excel connection manager. It might help to identify the version of the file.

Dynamic Source: Excel Connection SSIS

Here's what I'm doing:
I'm using a Foreach Loop container to grab any .xlsx files in a specified folder and assigning the fully qualified name to a variable called FileName.
Then I have a data flow with an Excel source importing to an OLE DB Destination.
How do I make the excel source the FileName variable?
--When I create the same process for flat files I have no problems creating an expression and changing the delay validation to true but when I try excel files it doesn't work the same. I've been able to work around the problem by using a file system task to move the xlsx files to a new folder giving it a static name and importing from that file, but I'm tired of doing that. Any help will be greatly appreciated!

Load excel file that changes name with SSIS

So I have a folder in which excel files get loaded daily. I need to create a package that extract those files to a sql table. However, the file changes name daily as the name comes with the current date,so the filename would be like filename+currentdate(name20140801.xlsx).
I tried using a variable that has filename?.xlsx/filename?*xlsx as a excelpath property for the excel connection manager but the task gives me an error DTS_E_CANNOTACQUIRECONNECTIONFROMCONNECTIONMANAGER.
Does anyone know how i can do this using the Data Flow task( I am trying to avoid Script task)
Thank you!
