What Our Users Say

"I could not live without it."

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.

-Umar A.

"... 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.
