Athena Asset Tables

Paid · Coming soon

Edit fast. Apply with confidence.

The Asset Tables window showing eighteen monsters as rows: each with a pixel-art portrait, kind, health, damage, speed, the sprite of what it drops, a colour swatch for its tint, and its hit sound drawn as a waveform with a play button.

A bestiary as a spreadsheet: portraits, dropped items, tints, and hit sounds beside every number. Sprites and sounds by Kenney, CC0.

Balancing a game means touching hundreds of ScriptableObjects, and the Inspector shows you one at a time. Athena Asset Tables puts every asset of a type in one table, with its portraits, icons, colours, and sounds drawn in the cells, and lets you work it like a spreadsheet: multi-column sort, AND/OR filters, keyboard editing, copy and paste, fill-down, saved views you can commit to git. Select forty rows and edit one cell, and all forty change.

Recipes do the math: add reward 5, multiply health 1.5, clamp speed 2 5.5, round, or copy one field into another, over exactly the rows you choose, and save the recipe for next time. Nothing you do writes a file. Every edit, paste, recipe, and import lands as pending cells showing before and after, with a summary bar, until you press Apply. A stale check refuses to apply over an asset that changed underneath you.

Apply is one Undo, however many rows it touched. A timeline lists every apply and reverts any of them, snapshots compare the table with an earlier state, and a journal restores every file byte for byte if Unity stops mid-write. Import CSV, TSV, flat JSON, or a shared Google Sheet through an explicit mapping in any column order; export round-trips exactly. Validation rules flag bad data in the table and gate the build. It also covers prefab components, materials, import settings, sub-assets, lists, and [SerializeReference] fields, with no page caps and no runtime dependency.

What it does

Pictures and sounds in the cells

Sprites and textures show as thumbnails, colours as swatches, curves and gradients as drawings, and audio clips as waveforms with a play button. Swap a portrait or a sound like any other value: staged, marked with what it was, and one Undo away.

Recipes: batch math without code

Add, multiply, clamp, round, set, or copy one field into another, over selected rows or every filtered row. Save recipes, reload them, and run them headless from the command line for a JSON report.

Staged, never silently written

Edits, pastes, recipes, and imports all become pending cells with the old value struck through and the new one beside it, plus a summary of the batch. Apply writes; Discard drops. A stale check stops an apply over an asset that changed since.

Edit forty rows with one keystroke

Select rows and edit one cell to set them all. Sort by several columns, filter with AND/OR conditions, hide, move, and resize columns, and keep it all in a saved view that lives in git.

One Undo. A timeline. Snapshots.

A recipe over ten thousand rows is a single Undo. The timeline lists every apply and can revert any of them, and named snapshots compare the table with an earlier state and restore it through the same preview.

Survives a crash

A recovery journal keeps the original bytes before the first write. If Unity stops mid-apply, the next session puts every file back exactly, and never overwrites a file that changed since without asking.

Spreadsheets in and out

CSV, TSV, and flat JSON through an explicit column mapping in any order, with columns you can ignore and GUID or key identity. Load a shared Google Sheet by link, no sign-in. Export round-trips exactly, and unmatched rows can create assets as a previewed step.

Rules that gate the build

Required, range, unique, and pattern rules in the view or on the field with an attribute; [Range] and [Min] count too. The data check runs before every build and from the command line in CI, and can warn or stop the build.

No page caps

A virtualized table with no paging. On a Ryzen 5 9600X with Unity 6000.6, 10,000 assets load in 1.4 seconds and filter in 22 ms; at 20,000, Apply time grows in a straight line and one Undo still takes 0.2 s. Long applies show progress and cancel with every file restored.

Privacy

Athena Asset Tables runs entirely inside the Unity editor. It collects nothing, sends nothing, and needs no account or network access.
