The lightweight yet powerful CSV Editor for your Mac.

Tabular data is everywhere and developers have to deal with sometimes very huge CSV data sets. But the Mac lacks an editor, that is capable of handling these CSV files in a fast and user-friendly way. Tablecruncher is the tool to open, edit, convert, export and save all kind of CSV files, no matter how large they are or what encoding they use.

New New beta version published on June 12th, 2019.


Open files bigger than 2GB and containing more than 15 million rows. Opening a 100MB CSV file with more than 500,000 lines takes less than 5 seconds on a dual-core Macbook Pro.
Use Javascript as a macro language to manipulate your CSV files. A simple API gives you access to all cells and you can change cell content as well as do abitrary calculations.
Export your table data to JSON. The exported JSON is an array-of-objects if there's a header row present in your CSV data. Otherwise you'll get an array-of-arrays.
Automatically detects most CSV file formats and file encodings for you. If you want, you can easily override the automatic detection and choose the appropriate CSV parameters.
Open and save CSV files with one of these encodings: UTF-8, UTF-16LE, UTF-16BE, Latin-1 (ISO-8859-1) and Windows 1252 files. (These list will be extended in future updates.)
Modify your CSV data grid easily. You can sort lines alphabetically or numerically, move columns right or left or delete columns. Or set your first CSV row as a header row.

What's the newest version?

At the moment beta is the most up-to-date version. This beta version will work until July 31, 2019.

What are CSV files?

CSV files are text files containing tabular data. The fields of the tables are separated by a special character, usually a comma, while a line break denotes a new record. The abbreviation CSV stands for Comma Separated Values.

Where's the formal definition for CSV files?

There is no formal definition, it's an ad-hoc-format. There exists an RFC 4180 that describes a best practice approach, but it's in no way an official formal definition.

Does Tablecruncher run on macOS Mojave?

Yes, the application runs on macOS 10.14 called Mojave. Dark mode is supported, but the appropriate theme has to be chosen manually.

What language and frameworks did you use to create Tablecruncher?

Tablecruncher is written in C++11, using the GUI framework FLTK. UTF-8 handling is provided by UTF8-CPP and Boost Locale. Duktape is the Javascript interpreter for the macro language and the JSON export routines are from Niels Lohmann's JSON libary.

Why does Tablecruncher not look like a typical Mac application?

To achieve the best possible performance, I decided to use C++ and the extremely fast FLTK toolkit. So, Tablecruncher is not written with an Apple-only tech stack. Result is a really fast application, but I know it never will win any design price. It aims to be a tool and like real tools it's not necessarily beautiful.

I miss a feature. How can I request it being implemented?

Just send an email to info@tablecruncher.com. I'll be happy to include it on my ever growing list of planned features, but make no promise that it'll ever be implemented.

The Story So Far: Some Milestones

The main features that are on my roadmap for 2019.

Looking like just another beta version, 0.9.7 transforms Tablecruncher into a powerful tool for manipulating CSV data.

Beta 0.9.2 published

Apr 1, 2018

I've just published 0.9.2 beta containing several minor bug fixes. Please continue testing and I'll appreciate your feedback!

Public Beta test started today

Oct 19, 2017

Today the first public beta 0.9.0 has been released. I'm very excited and looking forward for your feedback. Happy testing!

A name for my CSV editor

Aug 18, 2017

I have now used my internal versions for nearly a year, and soon will be the day to start beta testing my application. So I finally needed a website as well as a name. Choosing a name for your application isn't really easy. Finding names is the fun part, but checking available accounts and researching legal concerns is extremely time consuming. After having played with a dozen ideas, I now settled for Tablecruncher.
I hope the name describes well enough, what I want my editor to do: To easily crunch all your tabular data in all the CSV files that you get in your projects from different sources.

First internal Alpha Build

Oct 23, 2016

More than a year later, I now have a working early alpha version. As performance is one of my major concerns, the CSV editor is written plain C++ using the FLTK framework. The FLTK table view widget handles really large tables extremely well and the editor is impressingly fast.

I just started to work on an CSV editor for the Mac

Jun 15, 2015

As I'm working on several projects where a lot of data from different databases or spreadsheet exports is involved, I'm lacking an editor on my Mac that can easily handle large CSV files, guess the correct format and open documents with the right encoding. Always looking for an excuse to avoid my day to day work, I started writing my own CSV editor today.
