Import data from excel spreadsheet to django model - python

I'm building a website that'll have a django backend. I want to be able to serve the medical billing data from a database that django will have access to. However, all of the data we receive is in excel spreadsheets. So I've been looking for a way to get the data from a spreadsheet, and then import it into a django model. I know there are some different django packages that can do this, but I'm having a hard time understanding how to use these packages. On top of that I'm using python 3 for this project. I've used win32com for automation stuff in excel in the past. I could write a function that could grab the data from the spreadsheet. Though what I want figure out is how would I write the data to a django model? Any advice is appreciated.

Use http://www.python-excel.org/ and consider this process:
Make a view where user can upload the xls file.
Open the file with xlrd. xlrd.open_workbook(filename)
Extract, create dict to map the data you want to sync in db.
Use the models to add, update or delete the information.
If you follow the process, you can learn a lot of how loading and extracting works and how does it fits with the requirements. I recommend to you first do the step 2 and 3 in shell to get more quicker experiments and avoid to be uploading/testing/error with a django view.
Hope this kickoff base works for you.

Why don't you use django-import-export?
It's a widget that allows you to import excel files from admin section.
It's very easy to install, here you find the installation tutorial, and here an example.

Excel spreadsheets are saved as .csv files, and there are plenty of examples and explanations on how to work with them, such as here and here, online already.
In general, if you are having difficulty understanding documentation or packages, my advice would be to search for specific examples or see if whatever you are trying to do has already been done. Play with it to get a working understanding, and then modify it to fit your needs.

How to best share updated html and csv files created in a Juypter notebook with colleagues

What exactly I am doing: updating a predictive model with new data bi-weekly, and then updating the csv file and plotly graphs (html files) that contain the new predictions
What my problem is: right now I am sharing these updated predictions either ad hoc over email or by uploading the files to google drive (or my often both). Neither is a very good solution so I am looking for a better way to programmatically update these files and share them with my colleagues
My ideal solution: a link I could share that would open a web page with all of this data updated. The link could either be something that you can't find without being given the exact link or something that required a username and password to access
Decent enough with python for data analysis and visualization but no experience deploying web apps. Thanks in advance

How to extract serialised data from Access

I want to enable a user to export some data to a web application I am building. The data from the legacy application can be accessed through MS Acces (ODBC). The web application is written in Django/Python, but that is not very relevant.
The user would have to export data from time to time and import it into the web app. The table structure in the web app more-or-less mirrors the one in the legacy application.
My question of how to get the data from Access to a format that is easily parseable in the web app. The data is from 5 different tables and interrelated. Is there a way to serialise the data from Access into an XML / JSON file? I know that you can do an XML export, but as far as I know that is limited to a query, so I wouldn't have the hierarchy... Is there a VBA library to help with the task?
You can reference Microsoft XML, v5.0 (or whatever version) in the Visual Basic Editor and create XML programmatically.
See
- Simple example
- Introduction to XML in Microsoft Windows (in depth example)
Answering my own question here. I did some googling and it looks like you can export data from a table together with selected other tables. For that, it is necessary to draw the relationships within Access.
That might also solve my problem (and without composing the XML manually). Will find out if this works and check back later.

Write Microsoft Word Doc with MySQL data

I'm programming a MySQL database with Web interface for remote access. I used Django as a framework. But now, I want to generate some reports using the MySQL data and modify them after generating. Therefore, I automatically think of exporting data to or importing from Word. The thing is, how I do this?
I have seen several options. One of them, using Python-docx, a library to generate docx documents in Python. I could have a problem with this, because the generated reports will be large, with lots of images, tables, pages, etc. I worked with xlsxwriter, and when the files were large it took long time to generate de xlsx. I don't know if Python-docx would be the better solution.
Other option is to import data directly from Microsoft Word, using some software for this concrete purpose or using a macro VBA. I have programmed some example code with VBA to import data of MySQL using connectors ODBC and it's immediately possible, but there is thousand of objects and classes of VBA Word to learn.
Exposed the problem, any tips or suggestions??? Thanks in advance!
Another option is to generate HTML & open as a word document.
If you take a document similar to what you want to generate & save as HTML you will see what word does. Take this file as a template for your documents

Python Excel - OpenPyxl Limitation

I recently started to automate a report at work using Python. Since my data was provided to me in the form of an excel sheet, I felt the best way to do this was to use an excel python module. My module of choice was openpyxl. It worked great, I've used it to perform calculations and organise my data ready to plot charts. Now here's the problem...
I know that you cannot update existing charts using openpyxl so that option went out the window.
What I then tried to do was link the data in my openpyxl spreadsheet to another spreadsheet containing the charts (which is then linked to my word document where the charts are to be displayed). So after doing this I ran my script and to my annoyance, the data links between my openpyxl spreadsheet and charts spreadsheet had been severed. I guess this is because openpyxl creates a new spreadsheet when you save using the save function links are severed.
My question is.. are there any ways to maintain the data links?
It is currently not possible to maintain links between files. I think it would be possible to keep them metadata but, for fairly obvious reasons, it won't necessarily be possible to validate them. This best way for this to happen would be through a pull request.
If you're on Windows you might look at using the Python for Windows stuff which will allow you to remote control the applications.

Insert a lot of products opencart script

I have a script in python in which I have all my products, descriptions , images, etc. Now I want to insert all this information in my Opencart theme. I try to find out how to save it all of this in the MySQl database. I know I have to use MySQLdb for python but I don't know in which place I have to save de name, the direction of the image, the image, the size....
I know that there is import/export modules. Maybe I have to install one of those modules and save my information in a csv file and then import it.
Which would be the most quick method to insert all of this? Is there any other method? Because the modules are quite expensive.
Thank you so much!!
Your best option in my opinion is to use an Import/Export tool (there are free ones available like the excel tool by JNeuhoff). It's fairly easy to use once you figure out what you are doing. The best thing to do is to clear all the default data that comes with an install, create a couple of products, categories etc and export via the import/export tool, see how it comprises the data, then start developing a script to generate the fields from your current store items to fill it. I would also recommend installing vQmod too so that you can install it without making core changes to your admin files
