HI;
I cannot connect a CSV file to a SpreadSheet when the file is open. Currently a have a csv log file that is being constantly updated. I was able to connect it a an Excel SpreadSheet by normal import from external source with refresh every hour. However, its a big file so I needed to produce the reports using EXCEL SQL. It will not allow me to connect to the file while it is open. It says that the MS Jet database engine cannot open the file'unknown'. It is already opened exclusively by another user or i need permission to view its data. If granting permission is he problem , where do I grant myself permission. On a standard Impor, I have no problems reading the file while it is open, but otherwise, get this message and cannot proce3ed. Any help would be appreciated. If I close the update program, I am able to run the queries, but not if the update is running.
Using MSO 2007 W7 x64
It will not allow me to connect to the file while it is open.
That's right, it won't - there is no way to change this.
You must find another way to solve your problem.
How big is the file? You may be able to make a copy to a temporary filename, and connect Excel to that instead.
It sounds like you are accessing a logfile. LogParser can read CSV. In any case LogParser has an excellent SQL-like syntax and can read CSV files much more quickly and reliably than ODBC. It is also programmable from Excel VBA (or script). Perhaps you can use LogParser to extract the values of interest and then load those into your Excel table instead.
I suspect your best solution will be to use the LogParser MSUtil.LogQuery object from Excel VBA, to extract the values of interest into your spreadsheet. Since I don't know what you are actually doing this is just a guess!
I cannot recommend LogParser highly enough - it is a wonderful tool, and can read just about every standard type of logfile, CSV, TSV, W3C, as well as plain text files and the windows NT event logs:

I have an excel worksheet with 10 tabs.
For each tab, the data is structured as follows:
All tabs follow this same basic structure.
In Power BI, when I go to "Get Data", and then choose the .xlsx file, I get the following error:
Unable to connect
We encountered an error while trying to connect.
Details: "The input couldn't be recognized as a valid Excel document."
This is very frustrating and I don't know how such a simple task cannot be accomplished in Power BI.
Thank you.
Such alert could appear when you try to use Power BI connector on Excel file. It's understandable if the source file is corrupted and can't be opened in Excel. However, it looks strange if Excel opens the file in question and shows nothing wrong.
Based on our experience above is usually means what something is wrong with XML scheme of the Excel workbook.
Mushup trace (Data->New Query->Query Options->Diagnostics->Enable tracing) could give some additional information, but often not enough to find the reason.
We had two main scenarios
XML scheme is not complete
Usually if Excel file was generated by third-party tool. Such tool could generate quite limited XML scheme which is enough to open the file in Excel and to work with it, but not enough for Power BI connector. As an example, trace log shows
[DataFormat.Error] The input couldn't be recognized as a valid Excel document.\r\nStackTrace:\n…
…
[DataFormat.Error] We couldn't find a part named '/xl/sharedStrings.xml' in the Excel package.\r\nStackTrace:\n…
Such case is easy to fix – it's enough to open the file in Excel and save it (without any changes) – Excel is clever enough to fix the scheme. For the routine regular tasks we use poweshell script which does exactly the same in background.
There is the link within Excel file which is not recognizable as valid
Usually if Excel file is synced/kept with some cloud storage. One of the variants, wrong link could appear with copy/paste from another such file. That could be active link in one of the cells; or the link within conditional formatting formula; or even the link which actually isn't used by Excel but kept somewhere inside the scheme. For example, in one of the files I found in Data->Consolidate->All references the link like
'\drive.tresorit.com#7235\Tresors….[file.xlsx]Sheet'!$AC$6:$AC$357
on the file which was deleted long ago and isn't used, but for some strange reason the link was kept within the scheme.
Unfortunately for such case trace log doesn't give enough information to localize the issue, it looks like
[DataFormat.Error] The input couldn't be recognized as a valid Excel document.\r\nStackTrace:\n…
…
nExceptionType: System.UriFormatException, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089\r\nMessage: Invalid URI: The hostname could not be parsed.\r\nStackTrace:\n
Perhaps I have not enough knowledge for more straight forward localization of the problem, but the only way is to exclude Excel file parts one by one and check if the issue disappeared. Another way could be to unzip Excel file and check if wookbook.xml or sheetNN.xml have something suspicious inside.
I have to run almost 50 queries daily for daily reports and copy-paste the data into Excel sheets. Is there a way to schedule a job on SQL Developer that exports data from all the queries in an Excel Workbook?
You could link the excel spreadsheets to your queries so they automatically update themselves.
Insert > Data from External Source. I do this with SQL Server a lot, and you can do it with Oracle too if you know the connection strings.
I would comment, but I dont have the rep yet.
I would advise using your operating system to schedule the task. Assuming that this is Windows (as you want to write to Excel) then you can use Task Scheduler to set off a cmd script or powershell script which can call SQLPLUS passing in a parameter for the the sql file that you wish to run. It would not be too difficult to output this to a CSV file which can be opened in Excel. If you actually need to write the data to a .xlsx (or similar) file then there are options (e.g. Python libraries that can do this), but it will not be as straight forward.
I am not sure exactly what part of this you need help with, so can I suggest that you consider the steps below, if you want to proceed do some research and have an attempt at each step and then post a question for each that you are stuck on with details of what you have tried:
Schedule a job from your operating system;
Write a script to call SQLplus and execute a .sql file;
Change query output to csv and redirect to file (or find a way to write directly to an Excel file if this is what you need to do);
I want to open spss .sav data files in Excel without opening the spss files (I don't want to convert spss data file into Excel file). I know this is possible using OLDB connection, but I don't know how to do this.
I converted sav to csv online: http://pspp.benpfaff.org/
(Not exactly an answer for you, since do you want avoid opening the files, but maybe this helps others).
I have been using the open source GNU PSPP package to convert the sav tile to csv. You can download the Windows version at least from SourceForge [1]. Once you have the software, you can convert sav file to csv with following command line:
pspp-convert <input.sav> <output.csv>
[1] http://sourceforge.net/projects/pspp4windows/files/?source=navbar
In order to download that driver you must have a license to SPSS. For those who do not, there is an open source tool that is very much like SPSS and will allow you to import SAV files and export them to CSV.
Here's the software
And here are the steps to export the data.
I help develop the Colectica for Excel addin, which opens SPSS and Stata data files in Excel. This does not require ODBC configuration; it reads the file and then inserts the data and metadata into your worksheet.
The addin is downloadable from
http://www.colectica.com/software/colecticaforexcel
You can do it via ODBC. The steps to do it:
Install IBM SPSS Statistics Data File Driver. Standalone Driver is enough.
Create DNS via ODBC manager.
Use the data importer in Excel via ODBC by selecting created DNS.
You can use online converter, developed by me at N'counter.
This is the easiest way to open SPSS file in Excel.
1) You just have to upload your file to SPSS coN'verter at https://secure.ncounter.de/SpssConverter
2) Select some options
3) And your converted Excel file will be downloaded
No information about your file contents is retained on our server. The file travels to our server, is converted in-memory, and is immediately discarded: We don't peer into your data at any time!
I tried the below and it worked well,
Install Dimensions Data Model and OLE DB Access
and follow the below steps in excel
Data->Get External Data ->From Other sources -> From Data Connection Wizard -> Other/Advanced-> SPSS MR DM-2 OLE DB Provider-> Metadata type as SPSS File(SAV)-> SPSS data file in Metadata Location->Finish
I have a system with an Excel spreadsheet template file which is used for invoicing. I would like the user to be able to click a button on an Xpage, which will then open the spreadsheet and enter the latest invoicing data in Excel. I don't mind if Excel is either the application on their machine or on the server, but my preference would be the application locally on their machine.
I've looked into Xagents, as I feel this is probably the answer. I know they can be used to create Excel but I have not been able to locate any mention of opening an Excel file, and entering data into specific cells.
Is this possible?
EDIT: you can use Apache POI for editing and creating Microsoft Office documents. This is a java project which gives you a handle to office documents and this can be used using java.
A good starting point can be the blog of Christian Guedemann from webgate:

The only way I KNOW and tried to write data from Notes to Excel is exporting the data to an HTML page and setting the Content Type accordingly (e. g. as described here (there are a lot more resources available for taht):
http://www.dominoguru.com/pages/developer2010_xpagexlsexport.html
I am not sure if this is of help but it seems that this project can help you:
http://www.openntf.org/internal/home.nsf/project.xsp?action=openDocument&name=ZK%20Spreadsheet%20for%20XPages
As far as I can see this project can load Excel files from XPages - and then it should also be possible to edit the files.
Besides that the only solution I can think of is a Notes Agent that is called from the XPage. This agent can then run in background and do all the excel stuff. After running, the XPage can show a link to the Excel file. Actually this is the solution I would consider to implement - but maybe others step in with better answers here.
You don't want to introduce a dependency on Excel in your application -- wouldn't work with an iPad front-end. Rather have a look at the ZK Spreadsheet, it will fulfill your needs.
However if you have to have Excel, then you need a roundtrip solution: load the Excel from an URL (probably generated by an XAgent (?) and save it back. The saving back part is the tricky one. Normal HTTP doesn't allow that. What you need there is a webDAV capable server. Watch out for a project on OpenNTF soon (just clearing IBM legal) that provides webDAV.
However the ZK Spreadsheet looks much better for your needs.
I have a sample database at the following URL --> http://www.nnsu.com/nnsusite.nsf/%24%24OpenDominoDocument.xsp?documentId=B65507CB2DE15B3286257986005F061D&action=openDocument
Download the APCC.nsf. This will allow you to create/read a new EXCEL spreadsheet and then stream the resulting file to the requesting browser. There is not need to have EXCEL or office installed on the Server.
THe examples create a new workbook, but you can also store a "template" on the server or in a notes document and use it as a starting point and then save it to a document or stream it to the requesting browser.
With Apache POI you can read/write to a spreadsheet using data from the notes document the process is initiated from.
ADO.NET works fine when it comes to reading tabular data from excel files, but one problem I often run into is that if the excel file is locked by some other user there is an exception when ADO.NET attempts to retrieve the data.
Is it possible to tell ADO.NET to read contents from the excel file even if it's locked? If so, how can it be done? Do I need to add something to the connection string? The extended properties of my connection string are:
Excel 12.0;HDR=YES;IMEX=1
I had similar problem and I could not find a solution. I ended it up with timer re-trying to connect to a file.
The problem lies in the database itself. In the end of the day it is only a flat file and ADO requires exclusive access to it. You probably need to migrate your solution to MS Access mdb file or a proper(ish) database (SQLite?)
