What Our Users Say
'An indispensable tool'
I have been using Modern CSV for more than a year now and, as a data scientist in Digital Humanities, I could not live without it.
The ubiquitous open data exchange format is CSV. Excel and LibreOffice Calc are capable to read and save CSV data, but they reach their limits very fast -- mostly when dealing with big amounts of data. This is precisely where Modern CSV has carved its niche: dealing with vast amounts of CSV data, transform them fast, and extract them to another data set.
An indispensable tool, highly recommended.
'... the most consistent and wonderful experience.'
Having tried almost every CSV editing program I could find, Modern CSV by far gives the most consistent and wonderful experience.
If you’re a programmer (who uses keyboard more often), you will be happy to find out there is a quick access to the command list you can type in and the ability to customize every shortcut, which makes editing so blissful.
'... a powerful EDITOR of a CSV/spread sheet.'
I have been using Modern CSV editor for several months. It performs the editing that I need. What I need is true editing, e.g. move columns or rows of data or select data that I am looking for. It is powerful enough to turn poorly written letters to proper acronyms. It can also select data you need to keep and remove data you don’t need. For example: a column has both numbers and letters, you want to keep the numbers and eliminate the letters. These features are examples of its many tools. I could provide many more examples, however the best description is: it is a powerful EDITOR of a CSV table/spread sheet.

How To Open & Manipulate Large (>100MB) CSV Files On A Mac
Have you ever struggled to open and manipulate a large CSV file on a Mac? 100MB? 1 gigabyte or greater? Extremely large CSVs bring most spreadsheet utilities to a halt or the computer. I set out to figure out how to open and manipulate these files in a free and somewhat accessible way that was fast and didn’t risk crashes.
As a software engineer with a history of supporting marketing teams, I often encounter extremely large datasets including customer segment exports or analytics event logs that can be larger than a gigabyte. A good text editor can open these large CSVs but you lose spreadsheet capabilities like rearranging columns and filtering data.
In this post, I’ve outlined the different ways I’ve tried to manipulate large CSVs and their results. I’m using a 2018 Macbook Pro with a 2.6 GHz 6-core i7 and 16 GB of RAM. If you would like to skip the story and go straight to the best free solution, please click here.
Numbers & Excel
Csv Text Editor For Mac
Numbers honestly performed the worst. It has a hard row limit that seemed to be independent of file size. This made it useless for my task. Google Sheets worked for some files but would tend to crash or hang past a certain file size. Excel for Mac performed well but it is a paid solution so I did not consider it viable for many developers. Typically, opening large CSVs is a relatively rare occurrence unless your a data analyst, so I tried to find a free solution that would work well. Additionally, Excel’s file size limit appears to be 2 gigabytes, so it won’t work well for anything larger than that.
Google released a handy tool now called OpenRefine that enables lots of handy data manipulation operations. I was hoping this would be my answer to manipulating large CSVs. However, it definitely started getting really slow and crashing with files greater than a hundred megabytes. This is based on my memory from several months ago, I may test to get some better data around when it starts to crash.
I found a great SaaS solution for the problem, called CSV Explorer. They built a web tool to solve this exact problem. They have a free plan that has a limit of 5 million rows. If your data is column-heavy, this may be a great solution. The paid plans support up to 20 million rows. It’s a great solution if you don’t mind paying. Like I said earlier in the post, I desired a free solution so I kept researching.
MySQL Import Using Sequel Pro
Many database management programs give you the ability to import a CSV file. I had Sequel Pro installed so I decided to give this method an attempt. Sequel Pro is a free MySQL graphical management application for Macs. It has a great CSV import feature because it will help generate a table based on the CSV automatically. Here is a quick overview on how that works:
- Select the database you want to import into (or create a new one) and then go to File -> Import…
- Select the appropriate CSV files and make sure the import settings match your file’s needs.
- It’s best practice to name the table the same name as the file. This is especially important if later importing a much larger file into the same table.
Just like the other methods, the program crashed or froze when sufficiently large files were attempted. Specifically, my 1.32 GB CSV made Sequel Pro crash instantly.
MySQL Import Using Sequel Pro and the Command Line (Working Solution)
Finally! I found a solution that works reliably for large CSVs. Additionally, you can do complex sorting, filtering, and transformation operations if you are proficient with SQL.
For the sake of this example, let’s assume we are working with a CSV file >1GB that is called very_large_nov_2019.csv.
First, you must create a CSV file contain only the first 10-20 lines of your large CSV file, we will call it very_large_nov_2019_abridged.csv. I prefer to use a text editor to open the large CSV and then copy and paste the first 10-20 lines into a new text editor window and saving that file with a .csv extension.
Csv Viewer Mac
Then, utilize the Sequel Pro import method described above. Make sure the table name matches the name of the original CSV file. In our example case, the table name should be very_large_nov_2019. Once the new table is created, go ahead and delete the rows in the table in preparation for the import of the large version of the CSV.
Csv Editor For Mac
Use the following command to import your CSV file. I have enclosed data you must change in brackets ([ ]).
The table name should match the CSV name. If you created the table using Sequel Pro, this should be easy to accomplish. If you need to use a table name that is different than the filename, you can create a symbolic link:
