What others say about us

I would highly recommend EmEditor for any intensive text-centric activity!

I’ve been using EmEditor for the last 3 years, mostly for ontology crafting. I chose that editor after testing a lot of different solutions, and the two major reasons for that choice have been: trueUTF-8 encoding, andunlimited size of documents (withlight speed loading). All the other solutions I tested were falling short of providing one or the other. Additionally, I came to appreciate the excellentplug-ins, the keenregex integration, the side by sidecomparison, etc. EmEditor is a complex software with a ton of features and I’ve lost my way a couple of times but Emurasoft has been each time immediatelyresponsive andhelpful. I wouldhighly recommend EmEditor as a first choice for any intensive text-centric activity.

EmEditor is my daily go-to editor for both text processing and coding

BACKGROUND:
I’m a software developer and text-editor fanatic. I’ve tried pretty much every Windows text editor that’s ever been released. I don’t just use them to their fullest for work, I love text editors onto themselves – not just as a mean, but also as an end. EmEditor (EE) has become my daily go-to editor for both text processing and coding for fun.

FUNCTIONALITY:
There isnothing that EE can’t do: that’s its main selling point. It’s packed with built-in functionality and let’s youextend thatcore functionality with scriptable macros. Think “UltraEdit’s flexibility without the slow-as-death macro playback”.
EmEditor also comes in handy in unexpected ways:forget Excel,EE is THE BEST way to work withCSV files. As of a few years ago, I’ve been using EE instead of Excel to quickly process data from my bank accounts and credit cards at tax time.
By the way,the “filter” functionextraordinarily useful, and I can’t remember seeing it in other editors: type a string and EE hides all but the lines that contain that string. Another, somewhat related setting isthe ability (Edit > Narrowing) to restrict the current editing area to a sub-portion of the current file.

QUALITY:
I’m a fullstack web dev, but I’ve done quite a bit of Windows dev. I’ve never seen a piece of software that leverages so wellall Windows APIs. You can tell that everything is done carefully and thoughtfully, even the most mundane functionality.
One of EE’s claims to fame is tobe able to open huge files. (I can attest that it does: opening a PHP log from a live server and see it open in under a second is something.)

EXTENSIBILITY:
For years, I’ve been using TextPad for its macros. The macros are saved in a binary format and they can’t be customized after the fact. In EE, allmacros are stored ineditable JS code with awell documented API.
Both of these mean that there’s pretty much nothing you can’t do with EE.

SUPPORT:
As far as I know, EmEditor is a one-man project. The upside is that Yutaka Emura, EmEditor’s creator, provides support himself.Receiving supportfrom the person who wrote the software is a treat. I hope that many people will buy what is not only objectively the best all-purpose editor on Windows, but also the only one that is actively developed, and has been uninterruptedly so for over a decade.

CONCLUSION:
Because of the size of my professional projects, I often have to work in full-fledged IDEs (JetBrains), which are comparatively slow and feel annoyingly non-native Windows. But whenever I can, I go old school and code in EE. It’s pure bliss.

EmEditor is Much More Than an Text Editor Program | Imagine and Let EmEditor Do It

I wanted a program that could openlarge files. EmEditor proved that this wasa very simple request compared to its capabilities.

It is much more than an editor program.

For many tasks I wanted to do, I had to buy different software designed specifically for that purpose or pay a monthly subscription fee. EmEditor freed me from needing any other software, by letting me do everything I need so far with its support and features that are unique and powerful.

One thing I am sure of is this: EmEditor is waiting for you to turn your imagination into reality.

The support they offer is as perfect as your imagination. All other companies can learn from this team about providing support.

Thank you to the whole team for helping me save time.

The Fastest, Most Convenient And Best Editor

After working a while with EmEditor, I just want to say it’s really the fastest, most convenient and best editor I’ve ever worked so far under windows. I’m really glad that there are still people who care about performance and short loading times!

Thanks a lot for this master piece of software and keep up the good work.
