TXTeditor

Github

TXTeditor is a Windows desktop editor for Diablo II / Diablo II: Resurrected style tab-separated `.txt` data files.

It is designed for editing large game data tables more comfortably than a normal text editor or spreadsheet. The app uses a canvas-rendered virtual grid, so it can handle large `.txt` files while keeping table-style editing, navigation, search, diagnostics, and save workflows in one place.

This is a personal project and may still have rough edges, but it is shared in case it is useful for other modders working with Diablo II data files.

Vector-LSP Support

TXTeditor 0. 4. 3 includes Vector-LSP runtime support.

The app is intended to work together with:

TXTeditor.exe

vector-lsp.exe

contrib\

keep these files together in the same extracted folder. Removing `vector-lsp.exe` or the `contrib` folder may disable or break Vector-LSP diagnostics and related features.

The bundled Vector-LSP rules have also been adjusted for the TXTeditor packaged environment, reducing some noisy or incorrect diagnostics caused by incomplete workspace evidence, schema gaps, plugin lookup assumptions, and bundled contrib layout.

This tool is focused on Diablo II / Diablo II: Resurrected style `.txt` data editing.

It is not an official Blizzard tool.

Back up your files before editing.
