I want to read data from a .rwd file into Python. The file contains data on wind energy from NRG systems. IS there a way I can write parsers for new file types in Python. Being a beginner I am not sure whether I am using the correct terms in the question, so please bear.
The data I am reading contains wind energy data from NRG systems. They have a converter which converts .rwd files to .txt but works only on Windows. They haven't given any more information about whether the .rwd is encoded or not.I basically want to read it through Python because I want the software to work on Windows.

I have a set of measurement data in .atfx format. I know it is possible to read this data with ArtemiS SUITE, but I would need to make some post processing in python. I tried to look into the files, but as I see, atfx is a header file (with an xml structure) that points to binary files, so I'm not sure how I could write a python script to decode that, or if it is possible at all.
Is there a way to open ATFX files in python or is there a workaround?
Thanks for taking the time to read my question.
I am working on a personal project to learn python scripting for excel, and I want to learn how to move data from one workbook to another.
In this example, I am emulating a company employee ledger that has name, position, address, and more (The organizations is by row so every employee takes up one row). But the project is to have a selected number of people be transferred to a new ledger (another excel file). So I have a list of emails in a .txt file (it could even be another excel file but I thought .txt would be easier), and I would want the script to run through the .txt file, get the emails, and look for any rows that have a matching email address(all emails are in cell 'B'). And if any are found, then copy that entire row to the new excel file.
I tried a lot of ways to make this work, but I could not figure it out. I am really new to python so I am not even sure if this is possible. Would really appreciate some help!
You have essentially two packages that will allow manipulation of Excel files. For reading in data and performing analysis the standard package for use is pandas. You can save the files as .xlsx however you are only really working with base table data and not the file itself (IE, you are extracing data FROM the file, not working WITH the file)
However what you need is really to perform manipulation on Excel files directly which is better done with openpyxl
You can also read files (such as your text file) using with open function that is native to Python and is not a third party import like pandas or openpyxl.
Part of learning to program includes learning how to use documentation.
As such, here is the documentation you require with sufficient examples to learn openpyxl: https://openpyxl.readthedocs.io/en/stable/
And you can learn about pandas here: https://pandas.pydata.org/docs/user_guide/index.html
And you can learn about python with open here: https://docs.python.org/3/tutorial/inputoutput.html
Hope this helps.
EDIT: It's possible I or another person can give you a specific example using your data / code etc, but you would have to provide it fully. Since you're learning, I suggest using the documentation or youtube.
I have a Django application where I give users a Excel file for them to give me dates, i ask them to give me the date in DD/MM/YYYY format (the one used in Latin America) The problem is that if the language of the Excel file is in English, it uses the MM/DD/YYYY format. So for example if they write 01/05/2022, when i open the file in my application i receive 05/01/2022.
So I want to know if there is a way to get the original language of the excel file, for me to put some conditions inside my application, or if i can get the original raw text of the file.
I can't change the format that the application uses (because I receive excel files that are mainly in the spanish language) or ask my clients to write the dates in a different format, or ask them to change the language of the file.
I am open for other type of solutions too.
An Excel file doesn't have a "language". The system that Excel runs on has settings for region and language.
Excel will store a date as a number internally, so if my system uses US English with MDY format, then May 5 will be stored as 44682 and if my system uses a language with a DMY, then May 5 will still be stored as 44682.
So, if you get the underlying numeric value for the date, you would not need to be concerned what format was used to enter it.
I have first time encoutered a .scd2 type file. I downloaded this file from a sensor database. And I need to view the measeurements to make analysis of te data. I know SCD means slowly changing dimensions but I have no idea how to open this type of data using python. It would be great if I could convert this file type to ".csv" or ".xlsx" to work with pandas. I searched the internet but I cannot find any information regarding this extension nor how to dealwith it.
I want to enter data into a Microsoft Excel Spreadsheet, and for that data to interact and write itself to other documents and webforms.
With success, I am pulling data from an Excel spreadsheet using xlwings. Right now, I’m stuck working with .docx files. The goal here is to write the Excel data into specific parts of a Microsoft Word .docx file template and create a new file.
My specific question is:
Can you modify just a text string(s) in a word/document.xml file and still maintain the integrity and functionality of its .docx encasement? It seems that there are numerous things that can change in the XML code when making even the slightest change to a Word document. I've been working with python-docx and lxml, but I'm not sure if what I seek to do is possible via this route.
Any suggestions or experiences to share would be greatly appreciated. I feel I've read every article that is easily discoverable through a google search at least 5 times.
Let me know if anything needs clarification.
Some things to note:
I started getting into coding about 2 months ago. I’ve been doing it intensively for that time and I feel I’m picking up the essential concepts, but there are severe gaps in my knowledge.
Here are my tools:
Yosemite 10.10,
Microsoft Office 2011 for Mac
You probably need to be more specific, but the short answer is, in principle, yes.
At a certain level, all python-docx does is modify strings in the XML. A couple things though:
The XML you create needs to remain well-formed and valid according to the schema. So if you change the text enclosed in a <w:t> element, for example, that works fine. Conversely, if you inject a bunch of random XML at an arbitrary point in one of the .xml parts, that will corrupt the file.
The XML "files", known as parts that make up a .docx file are contained in a Zip archive known as a package. You must unpackage and repackage that set of parts properly in order to have a valid .docx file afterward. python-docx takes care of all those details for you, but if you're going directly at the .docx file you'll need to take care of that yourself.
