Jul 20, 2019 Paid CSV File Readers for Mac: Easy CSV Editor. Easy CSV Editor provides all the basic functionality that you would expect from a CSV reader. In addition to basic features, it offers many advanced functions like sort, split, merge, works with broken CSV files, auto-detects the field separator. Data merge is a very powerful tool. This tutorial will teach you how to easily import structured data, such as text and images in InDesign, in a matter of seconds by reading an external data source file in.csv or.txt file format.

Why do you need this?

Manually copy-pasting is fine if you don’t have too many files to work with.

But imagine if you have 100+ files to concatenate — are you willing to do it manually? Doing this repetitively is tedious and error-prone.

If all the files have the same table structure (same headers & number of columns), let this tiny Python script do the work.

Step 1: Import packages and set the working directory

Change “/mydir” to your desired working directory.

Step 2: Use glob to match the pattern ‘csv’

Match the pattern (‘csv’) and save the list of file names in the ‘all_filenames’ variable. You can check out this link to learn more about regular expression matching.

Step 3: Combine all files in the list and export as CSV

Use pandas to concatenate all files in the list and export as CSV. The output file is named “combined_csv.csv” located in your working directory.

encoding = ‘utf-8-sig’ is added to overcome the issue when exporting ‘Non-English’ languages.

And…it’s done!

This article was inspired by my actual everyday problem, and the coding structure is from a discussion on stackoverflow. The completed script for this how-to is documented on GitHub.
