Rowsmith — ScriptableObject Spreadsheet Editor

Changing the same field on three hundred assets is the kind of job the Inspector does one at a time. Rowsmith puts them all in one table inside the Editor, and shows the whole list of what will change before it changes.

WHAT IT DOES

- The table. Pick a ScriptableObject type and see every asset of it as a row. Nothing is paged, capped or trimmed; five thousand rows open at once and their values fill in behind you.

- Edit a cell from the bar at the bottom. A value that does not fit is refused with the real range instead of being narrowed, and every write is read back from the file and compared before it is allowed to stand.

- Edit many rows at once - set, add, multiply, or change by a percentage - with a line that states what will happen before it happens, and one Ctrl+Z that takes the whole batch back.

- Search and filter, and apply a batch to exactly the rows you filtered to and nothing else.

- Export to CSV - exactly the rows on screen. UTF-8 with a byte order mark so accents survive, and one setting that covers both separator conventions, so Excel opens it correctly wherever it is installed.

- Import a CSV back, with a review screen that shows every change - the stored value beside the new one - before a single asset is written. Rows are matched by GUID and columns by header name, so reordering either changes nothing.

- Assets whose script is missing are shown in red, next to their siblings, and any that fall outside are counted in the status bar - rather than quietly left out.

- Editor-only. Nothing but the optional sample data type is compiled into your build, and deleting the Samples folder removes even that.

HOW IT WAS BUILT

Every number published for this tool was measured, not estimated. Where nothing was measured, no number is written. The limitations listed under Technical details are there on purpose: a tool that hides what it cannot do costs you the afternoon you spend finding out.

WHAT IT TOUCHES, AND WHAT IT DOES NOT

- It works offline. No network access, no telemetry, no account, no activation.

- It reads .asset files under Assets/. It does not read Packages/.

- It exports only to the file you pick in the save dialog, and imports only the file you pick.

- A batch edit or a CSV import changes your assets only after showing you exactly what will change and having you confirm it.

- As with any bulk edit, having version control or a backup is worth the minute it costs.
