重stacked箱box
じゅうばこ · joo-bah-koh
noun Lacquered boxes that stack into one. One file, several tables.
Microsoft Access, without the hard parts.
orders_FINAL_v7.xlsx or orders (2).csv? Which one is right?
Put them in one box. Make a database, put a spreadsheet in it, look at your rows, print a tidy list. No SQL to learn, no server to set up, no account to make.
Drop a CSV or Excel file on the window. Jubako works out each column (words, whole numbers, decimals, dates, yes/no) and shows you its guesses before anything is written. A workbook with several sheets can become one table per sheet.
A database is one .jubadb file: copy it, back it up, email it. It's ordinary SQLite, so
nothing is locked away. Already run PostgreSQL or MySQL? Point Jubako there instead.
Add a field, rename one, delete one. Delete a table or the whole file. The destructive ones ask first.
A grid of everything in a table. Tap a row to pick it, double-tap a cell to change it.
“Show rows where Category contains bike” hides the rest. Save a rule you keep using, like “Still here”, and it lives inside the database file.
A form for every table. Previous, Next, Save, New row.
Pick the columns, a title, the page size. Columns shrink and wrap so the whole table fits. One layout paints the preview, the PDF and the printer, so what you see is what prints. Export to CSV, Excel or PDF.
Jubako reads your Omarchy theme and follows it, dark or light, with your accent colour. Change theme and the open window changes with it.
An MCP server and a command line do the same jobs as the window, so “turn this spreadsheet into a database” just works from Claude Code or any MCP client.
$ jubako new "Harbor Cycles" ~/Documents/harbor-cycles $ jubako import ~/Documents/harbor-cycles.jubadb book.xlsx --all-sheets $ jubako report ~/Documents/harbor-cycles.jubadb orders orders.pdf --landscape # or let an agent drive it: claude mcp add jubako -- jubako-mcp
Packages for Arch and Omarchy, Debian and Ubuntu, and Fedora. They use your distro's Python and Qt, and put Jubako in your app launcher.
