I'm currently working on a project (developed using laravel, php, javascript, jquery, html), containing a large amount of data, so I'm using DataTables to display them with serverside set to true. What I'm trying to figure out is how to export the complete table to an excel file - right now it only saves one page (the one being shown at that very moment ) - using the Button extention.
I've been reading about it for a while now but still can't figure out a way to do this. I understand that, since serverside is set to true,
the only rows that exist on the client-side are those shown in the table at any one time.
But how can I get the complete table? Any help would be appreciated!
UPDATE:
So I create the excel file with the data I want in the backend, using PHPExcel, but now the problem is that it is saved server-side, while I wanna make it downloadable (client-side). From what I've been reading, I must add the appropriate headers to do so, but nothing I've tried works. Using
this, I managed to output the data of the excel in the screen, but it just shows gibberish... I should probably also mention that I'm new at this!

I am new to Tabulator and started building my first project. While usage and setup is very intuitive and nicely built I struggle with one concept. I want to keep changes and entries I made to the table and load them again when re-opening the page.
My first thought was to download all entries as csv or xls and then import either from an array/JSON or from an HTML table. Is this the preferred way or is there another method I can use?
Thanks!
Note: I am using version 4.1
Tabulator doesn't include what you are looking for. However, you can use Tabulator to retrieve the table's values. As for saving and restoring the edited data, you may want to use your browser's localStorage: https://developer.mozilla.org/en-US/docs/Web/API/Window/localStorage
I am trying to set up tabulator with all it's data validation goodness and simple to use UI in order to help a colleague with CRUD operations on a .txt file he has to do on a daily basis.
I found that tabulator can load data using AJAX but my question is, is it possible to load the data from a .csv/.txt file and then save to the same file?
I know you can export to .csv but without overwriting the loaded data, next time all his work would be lost.
If you are referring to a file on a users local computer then im afraid there is no import from file functionality built in to tabulator, but there is nothing to stop you implementing that bit your self.
The link below is a link to an article that explains how to load a CSV file from an input element in JavaScript,. In the example it loads it into an HTML table, but you could easily alter that to dump it into an array of objects to pass into Tabulators setData function

In terms of saving the data back to the users computer, you would need to use the built in download function, there is no way to save it back to the users computer without the file popup due to browser safety constraints.
But i will add that the above approach is a bit unorthodox. The usual way to handle data persistence would be to save the data back to your server into a database, and then load it back to the client with an ajax request, giving the user the option to download the data when they want the final copy
So, there is this website where I have to log in and insert values in the add content->person roles and I have to take values from an excel file. I tried entering the values in the database directly but got nowhere. The database is too randomly generated.
I want to know- how to go by this problem? I think python would be the best way but I am more comfortable with java. The images bellow will help understand the situation better-
The log in from:

Try using feeds module:
https://www.drupal.org/project/feeds
Install it on you site first of course. Or look for some similar import module. Maybe this one:
https://www.drupal.org/project/datasources
If nothing succeeds then try making import script on your own. You have to parse document (would be much easier to open it from excel and export as CSV if possible http://php.net/manual/en/function.fgetcsv.php) and have some loop to write content into Drupal system. Use Drupal's functions for that, do not directly write to database. It's not hard as it looks like:

Log data from a test is uploaded to a web service, and the processed CSV is downloaded back into Excel for viewing in charts. At the moment, this is done via copy and paste for short CSV files and the Data > From Text feature for larger CSV files. Unfortunately, this takes a bunch of time for every test, and I need to make the process very simple for someone else to update the Excel spreadsheet.
The Excel spreadsheet contains 5 raw-data pages which are used to store the CSV from the server. I have no issues selecting Data > From Text, entering the website URL, and completing the format to import. This process can be repeated (same as the Copy and Paste) for all 5 pages to import the data.
This process only allows me to put in one filename, so I am using the same URL for the data, and having PHP return the CSV of the latest (or a specifically configured) test whenever the website is accessed. I've verified that this process is working correctly.
Unfortunately, when I do 'Refresh All', it prompts for a filename unless I go to Data > Connections > Properties, and uncheck 'Prompt for file name on refresh'.
However, even when I do that, I'm getting mixed results. Sometimes only one of the pages will update. (Seems to be the last one I set up.) Sometimes none of them do. I need a solution which updates all 5 pages based on the current CSV from the server without having to set up the connections again every time. Ideally I'd like to just hide these raw data sheets so we can have an Excel file that's just the final charts.
Surely this is a common function and I am doing something wrong, yet all the guides I try on the Internet don't seem to work. For example, this one:
http://www.kimgentes.com/worshiptech-web-tools-page/2010/8/18/web-connecting-csv-files-as-external-data-to-excel-spreadshe.html [URL is corrected]
Seems like they only set up one connection. I can get one working to refresh, but not more than one.
I have seen this happen and finally figured it out. There are actually 3 things that can happen to give this result, and a separate solution for each:
First, Excel software uses the IE 11 web object to when it does web
retrieval of data. This means it will be "sticky" to sessions using
IE11 to access the data. Most websites these days are run by cloud
servers, which generate sessions on the server with the most load.
This normally has no impact on users on web browsers since they
login and can visually enter their credentials etc. But when a
program accesses a website and must use a specific web browser, it
must use the properties of that browser and how it works. I ran into
this a lot when I would generate and be able to download my CSV
files on the website in Chrome, then try to use Excel to import the
same files wouldn't work (it would say they weren't there). The
solution to this, at least for now, is to use IE 11, login to the
website, generate the CSV files and test that they can be
downloaded. Then use Excel to run the web import and it should pick
up the same sticky session to get the CSV files.
Second, password entry is a different thing, but also has to do with the stickiness
of the data. For some reason Excel will not cache your credential
responses for logging into a website without you entering them 3
times. This experience may change for you, but I found that I must
enter a new credential set (for a new web import of a CSV) 3 times
before it becomes permanently cached by Excel. After this, I don't
have the problem.
Third, most complex Excel programs that require
web import may also require that you either import local data you
downloaded from a website, import data from a website into a sheet
or run more complex objects like Macros. All of these need proper
permissions. You may need to set your Trust Center settings to allow
you to use your Excel program on your computer in this way. That is
part of MS office. You can set add and update those as per MS info

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.
