A workflow for reading, editing, formatting, and inspecting Excel spreadsheets through the ET Excel tool. Excel spreadsheets are files with sheets, cells, formulas, and tables.

Use it to update cells and ranges, manage sheets and formulas, merge headers, batch-transform data, and prepare Luban tables before export.

It provides the required project-safe way to modify Luban source spreadsheets and helps prevent malformed tables or missing merged headers.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00053	$0.01035
Opus 5	$0.00026	$0.00517
Sonnet 5	$0.00011	$0.00207
Haiku 4.5	$0.00005	$0.00103

Measured 13d ago against content hash 70d4f4edc89f, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-12, from the pricing page.

Security

Grade A, and why

et-excel scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 13d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

et-excel - ET Excel 入口

强制规则（重要）

只要涉及 Excel/xlsx 的任何读写操作，都必须调用 excelmcp（ET.ExcelMcp）完成；禁止手写脚本或用其它库/工具直接改 xlsx。
excelmcp 源工程位置：./Packages/cn.etetet.config/DotNet~/ET.ExcelMcp。
运行入口（编译产物）：仓库根目录 ./Bin/ET.ExcelMcp.dll，统一在仓库根用 dotnet ./Bin/ET.ExcelMcp.dll ... 调用。
若 ./Bin/ET.ExcelMcp.dll 不存在（没有可执行文件），先编译工程再操作：
```
dotnet build "./Packages/cn.etetet.config/DotNet~/ET.ExcelMcp/ET.ExcelMcp.csproj" -c Debug
```
产物会输出到 ./Bin/ET.ExcelMcp.dll（csproj 的 OutputPath = $(RepoRoot)Bin，RepoRoot 即仓库根）。

何时使用

通过 Bin/ET.ExcelMcp.dll 读写 Excel
处理单元格、区域、样式、公式、图表、工作表
做批量数据导入导出、筛选、排序、合并单元格
维护 Luban 配置表内容，但还没有进入导出阶段

不要加载

只是编译、跑测试、做 Unity 编辑器操作
只是执行 Luban 导出，不需要实际读写 Excel（用 et-luban）
只是讨论表结构，不需要实际读写 Excel

默认动作

先 cli list 或 cli help <工具名>，不要硬背完整工具表。
能批量就批量，优先 excel_range / excel_data_operations，不要逐格操作。
JSON 参数只传本次调用最小字段集；pwsh 中优先外层单引号。
写操作优先使用绝对路径；覆盖原文件前先确认目标文件。
维护 Luban __beans__/__enums__/多态数据表时：用 excel_data_operations batch_write 只写非空格（空行真空）；写完必须 excel_merge_cells merge 合并"列表"表头（*fields J1:P1、*items H1:L1、多态字段表头跨子列宽），否则 Luban 导出报缺 alias 列；含中文走 Write→UTF-8 Python→ExcelMcp，读回校验合并用 get_merged、文本用 ascii()。完整格式见 et-luban。
改完表如果需要生成配置产物，再叠加 et-luban。

配置约定（项目规范）

资源类字段只填资源名：不写完整路径与后缀；表里若出现 Assets/.../xxx.prefab 这类完整路径，应收敛为 xxx（加载侧按名字 LoadAsset）。
新增配置表必须注册 __tables__.xlsx：补全 Category / value_type / input / index / group，否则 Luban 导不到这张表。
改完表必须导出，且优先定向导出：只导受影响的配置数据/代码（如对应 GameConfig 的 s / c / cs），避免全量导出超时；导出与导出后 Unity 刷新走 et-luban。
写中文必须二次验证：读回或检查 xlsx 的 sharedStrings.xml，不要只信终端输出（详见 references/et-excel-cli.md 的「中文写入防乱码」）。

优先入口

dotnet ./Bin/ET.ExcelMcp.dll cli list
dotnet ./Bin/ET.ExcelMcp.dll cli help <工具名>
dotnet ./Bin/ET.ExcelMcp.dll cli <工具名> '<JSON参数>'

Files

What ships with it

4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
