how to open a very large csv file

Hello,

I need some help to open a 16gb csv file, how much RAM or CPU do i need in my pc to open it? Thank you !!

 

Try these 2 programs: UltraEdit and EmEditor

You can try on NotePad++

 

Or you could try kiwix. 16gb is too large for Notepad ++ because it wouldn't work for my downloaded wikipedia copy (10gb), but kiwix did. Though I'm not sure if kiwix supports all files.

 

depending upon your requirements , you could also use command line tools to do the job. like grep

 

I'm assuming that you're on Windows, so I'll recommend gVim. Where Notepad++ will choke on very large files, VIM has chowed through those puppies with little problem.

 

There is a solution in Excel. You can’t open big files in a standard way, but you can create a connection to a CSV file. This works by loading data into Data Model, keeping a link to the original CSV file. This will allow you to load millions of rows.

 

You can try Notepad++ and Subline text.

 

I would recommend Looker as the solution for datasets larger than old excel can cope with.

 

The amount of RAM or CPU you need to open a 16 GB CSV file will depend on the size of the data contained in the file and the capabilities of your computer. Here are a few factors to consider:

• The amount of data contained in the file: A CSV file is a simple text file, so the size of the file itself doesn't necessarily reflect the amount of data it contains. If the file has a lot of data, it may require more memory and processing power to open and manipulate it.
  
  
• The capabilities of your computer: The amount of RAM and CPU available on your computer will also affect its ability to open and work with large files. In general, more RAM and a faster CPU will allow your computer to handle larger files more efficiently.
  

As a general rule of thumb, it's a good idea to have at least 8 GB of RAM and a relatively fast CPU (such as an Intel Core i5 or higher) to work with large files like a 16 GB CSV. However, the specific requirements may vary depending on the complexity of the data and the specific software you're using to open and manipulate the file.

If you're having trouble opening a 16 GB CSV file on your computer, you may want to try using a tool specifically designed for working with large datasets, such as Apache Spark or Google BigQuery. These tools are designed to handle very large datasets efficiently and can make it easier to work with large files like a 16 GB CSV.

 

1. Spreadsheet software: You can open a very large CSV file using spreadsheet software such as Microsoft Excel, Google Sheets, or LibreOffice Calc. These programs can handle large files and allow you to sort, filter, and analyze the data.
   
   
2. Text editor: You can open a very large CSV file using a text editor such as Notepad++, Sublime Text, or Atom. These programs can handle large files, but they may not be as user-friendly as spreadsheet software and may not have built-in data analysis tools.
   
   
3. Command-line tools: You can use command-line tools such as sed, awk, or grep to open and manipulate very large CSV files. These tools can be powerful, but they may require some knowledge of programming or scripting.
   
   
4. Open source libraries: You can use open source libraries such as pandas or Dask to open and manipulate large CSV files. These libraries are designed to handle large data sets and can be used with programming languages such as Python.

 

This is the best reply.

But you can also just import in into mysql or sqlite and then use phpmyadmin, adminer or sqlite explorer to browse the data (that's what i would do)
