Klados Klados
Install Klados with WinGet
winget install --id=klados.Klados -e Klados shows a data file three ways, kept in sync: its structure as a tree, the selected node's contents as tables, and the source text exactly as it is on disk. Repeating children become a grid you can sort, filter and export. Editing happens in the source, and saving writes the file byte for byte, in its original encoding.
