Bringing readability and efficiency to legacy EDI workflows

Problem: A senior software developer at a health insurance company struggled with managing and editing thousands of EDI (Electronic Data Interchange) files. They were written in an antiquated, data format with poor readability.

An editor that eats through large files

Problem: Developers and IT professionals often struggle with editing massive log files, data sets, or source files. Most editors and IDEs choke on large files, requiring plugins, special tweaks, or giving up entirely.

Solution: UltraEdit is built to open, search, and edit files of virtually any size straight out of the box. No plugins, no special configuration—just fast, reliable performance without limits.

“Large files can be edited much faster in UltraEdit compared to other editors - a must-have feature for quickly changes in large EDI files!”
