Tablecruncher

CSV Editor for Mac, Linux and Windows — Fully Open Source

April 29, 2025 Tablecruncher is going Open Source — and cross-platform

Finally, after neglecting this product page way too long:
Big news for Tablecruncher!

The fast, native CSV editor for Mac is going Open Source (GPLv3) — and will soon run on Windows and Linux, too.

The Mac version is already available for free. The open-source launch and cross-platform builds will follow in May.

Why open source?

After selling Tablecruncher to users in over 70 countries, I reached a crossroads: either turn it into a full-blown business — or find a more sustainable way to keep improving it without going all-in on commercialization.

Open-sourcing Tablecruncher felt right. It lets me keep helping people who deal with messy data every day, and make the app available to an even broader audience.

💬 If that sounds good to you and you'd like to support me and the project, please ⭐ star the GitHub repo to follow along.

Thanks to everyone who supported the project so far — more soon.

August 7, 2019 Got covered in german Mac online magazine today

Today, Tablecruncher got covered in a short piece in the german Mac online magazine ifun.de. Having done press relations the last time about 25 years ago for a completely different industry, I'm extremely out of practice. So it was by coincidence I got this reference.
I'm following this magazine to stay up-to-date in the Mac world and yesterday I saw a short comparison of text editors and how they're dealing with CSV files. I took this opportunity to tell them about Tablecruncher, and today they already mentioned it!

June 28, 2019 Tablecruncher launched

Nine public beta versions, more than 10,000 downloads and a lot of invaluable feedback from beta testers later, I finally launched Tablecruncher.

To sort out all the small details took a lot of time, much more as I thought it would. While the core of the application has since long been ready, the UI and some smaller features weren't. And of course there were tasks I never considered. For example, Apple came up with the idea of notarizing apps. So I had to include notarization into my build process.

October 19, 2017 Public Beta Test started

After having worked for about two years on what once was a CSV viewer, became now a CSV editor. And I decided to eventually sell it as classical standalone desktop application for macOS. To improve the application and to get feedback from user, in October 2017 I started a public beta test.

I thought it should take about half a year. I was wrong, though.

October 1, 2015 Started to work on a CSV Viewer

I often had to deal with CSV files, but there was no CSV viewer for the Mac. And I was looking for a project to refresh my old C++ skills and learn a cross-platform GUI toolkit. So I started to work on this side project whenever my job as a freelance online marketing consultant permitted it.

I needed a fast, native CSV editor for Mac — but couldn’t find one I liked. So I built Tablecruncher. It started as a personal tool, grew into a paid app, and is now open source to help even more people handle messy data
