The ALV has 140 columns and the number of records can be around 50K or more. So, when processed in background I want to export the ALV records in either XLS or CSV file. But I heard that XLS has a limitation of 50K records. Is there any such limitation on CSV file as well? If yes, what is the limitations? Please help!! Data Engineer at CSV ExplorerCSV files are chunks of text used to move data between spreadsheets, databases, and programming languages. Spreadsheet software, like Excel, can have a difficult time opening very large CSVs. I’ll explain why large CSVs are difficult to work with and outline some tools to open big CSV files. If you're looking to open a large CSV file, CSV Explorer is the simplest and quickest way to open big CSV files. The Difficulty with Opening Big CSVs in ExcelSpreadsheet software, like Excel and Google Sheets, work by loading entire files into a computer's high speed memory (RAM). Excel is limited to opening CSVs that fit within your computer’s RAM. For most modern computers, that means a limit of about 60,000 to 200,000 rows. Google Sheets runs on Google computers with more RAM and can often open slightly bigger CSV files. The ToolsDatabases and programming languages are able to open enormous data sets by bringing small chunks of a file into RAM as they're needed. Below, I'll outline some popular databases and programming languages to open large CSVs such as shells, SQL databases, & Python. ShellsShells are computer applications for running software commands. They are good for getting samples of the data and basic searching. They aren't good for numerical analysis. Mac, Windows, and Linux computers all come with a shell installed. Mac computers come with the Terminal application. Windows comes with PowerShell. Here are some popular commands for working with big CSVs in the shell. Windows PowerShell
Mac Terminal
SQL DatabasesSQL Databases are applications for querying, aggregating, and updating rows of data. They can be difficult to set up but are remarkably powerful. If you’re planning on using your CSV in a software application or connecting your CSV to a Business Intelligence tool, you should load your CSV into a SQL database. Many BI tools can import CSVs but the tools often have size limits. SQL stands for Structured Query Language and is a standard for querying data across many databases. The most Popular open-source SQL databases are MySQL and PostgreSQL. Loading a CSV into PostgreSQL or MySQL requires 3 (not-so-easy) steps.
Be sure to use the Microsoft AccessMicrosoft Access is Microsoft's desktop database tool. It comes with a user interface for importing CSVs and querying them. You can also write SQL in Access and connect Access to Excel. Access is included in the Microsoft Office Professional Suite or can be downloaded here. See Microsoft's documentation on importing CSVs into Access. PythonPython is a general-purpose programming language and contains many of the same functions as SQL. It's easier to load a CSV into Python than into a database. Python is the tool-of-choice for many data scientists and statisticians. There are several Python tools for working with large CSVs: the native CSV module, Pandas, and csvkit. CSV Explorer uses Python to parse large CSVs before loading them into a database. Python comes pre-installed on Mac computers, and can be opened by opening the Terminal and typing Other programming languages like R, SAS, and Matlab have similar functions for opening and analyzing CSVs. CSV ExplorerCSV Explorer is a tool for opening, searching, aggregating, and plotting big CSV files. Behind the scenes, it uses a combination of Python and SQL to open big CSVs.
The documentation will show you examples to search, aggregate, plot, and export to Excel. You can try CSV Explorer on your data here. Conclusion The tools for working with big CSVs are powerful, but not friendly to beginners. Using a Shell is a great way to get a sample of a large CSV and get started. For more complicated analysis, Python or a SQL database will give you much more power. CSV Explorer lies somewhere in the middle and is often a good first step for looking at big CSVs.What is the largest CSV Excel can open?Excel is limited to opening CSVs that fit within your computer's RAM. For most modern computers, that means a limit of about 60,000 to 200,000 rows.
Can CSV hold more than 1 million rows?CSV files have no limit of rows you can add to them. Excel won't hold more that the 1 million lines of data if you import a CSV file having more lines. Excel will actually ask you whether you want to proceed when importing more than 1 million data rows.
How do I make a large CSV file in Excel?So, how do you open large CSV files in Excel? Essentially, there are two options: Split the CSV file into multiple smaller files that do fit within the 1,048,576 row limit; or, Find an Excel add-in that supports CSV files with a higher number of rows.
Is there a limit on Excel file size?Maximum file size for rendering a workbook in Excel Services: 10 megabytes (MB) default. 2 gigabytes (GB) maximum (2)
