What Our Users Say

"The most consistent and wonderful experience."

Having tried almost every CSV editor 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. 

- Umar A.

"Superbly designed and highly functional"

Earlier this year, I was drafted into yet another project where I had to edit and organize a large amount of textual data, and those “big programs” kept corrupting the data by adding their own information.

In frustration, I searched (again!) for a better solution for working with files of “comma separated values” and I stumbled on Modern CSV.

It was amazing! It did pretty much exactly what I needed. If you deal with CSV files, try this program. It is superbly designed and highly functional, with a small system footprint.

- Rob W.

"I can recommend this tool"

I came upon ModernCSV when looking for a better altenative to Google Sheets/Apple Numbers for CSV editing. Modern CSV is a specialised tool for the job and it doesn’t try to interpret/format data from the file. You see what you get. I can recommend this tool for everyone working with CSV files on a regular basis.

- Torben S.

"The best!"

Thanks for great software! I recommend Modern CSV to everyone I know who works with data files.

I’m loving Modern CSV and tell every geek I know about it!

- Scott K.

"An outstanding product!"

I have tried so many different csv viewing/editing software for so many years (I have been programming for about 25 years) and have never found anything that checks all the boxes for me when working on complex software projects…UNTIL I FOUND MODERN CSV!

You have created an outstanding product!
