+**Search with Row Data (`include_row_data=True`):**
+
+Use `include_row_data=True` to get the entire row data for each match in a single call, avoiding N+1 reads.
+
+```python
+result = sharepoint_excel(
+    file_path="/sites/finance/Shared Documents/report.xlsx",
+    query="budget",
+    include_row_data=True
+)
+```

+{
+  "matches": [
+    {
+      "sheet": "Sheet1",
+      "coordinate": "B5",
+      "value": "Monthly Budget",
+      "row_data": [
+        {"coordinate": "A5", "value": "Category"},
+        {"coordinate": "B5", "value": "Monthly Budget"},
+        {"coordinate": "C5", "value": 50000}
+      ]
+    }
+  ]
+}
+```
+
+**Performance Guidelines:**
+- **Small scale** (<50 matches): Highly effective, recommended
+- **Medium scale** (50-200 matches): Effective, monitor response size
+- **Large scale** (>200 matches): Consider response size impact
+
+**Important Notes:**
+- `row_data` includes only non-null cells from the matched row
+- `row_data` does NOT include header rows (even with frozen_rows)
+- To understand column meanings, first read `A1:Z5` for header context
+- **Multiple matches in same row**: Each match gets independent `row_data` (duplicated)
+  - Example: If "budget" matches both A5 and B5, both matches will include the same row_data
+  - This ensures each match is self-contained but may increase response size
+
+**Verified Use Case:**
+- 23 matches processed in 1 call (vs. 24 calls without `include_row_data`)
+- Token savings: ~2,300 tokens
+- Response time: Significantly reduced
+

+**行データ付き検索（`include_row_data=True`）:**
+
+`include_row_data=True`を使用すると、各マッチの行全体のデータを1回の呼び出しで取得できます（N+1回の読み取りを回避）。
+
+```python
+result = sharepoint_excel(
+    file_path="/sites/finance/Shared Documents/report.xlsx",
+    query="予算",
+    include_row_data=True

+
+**パフォーマンス目安:**
+- **小規模** (<50件): 効果大、推奨
+- **中規模** (50-200件): 効果あり、レスポンスサイズに注意
+- **大規模** (>200件): レスポンスサイズへの影響を考慮
+
+**重要な注意事項:**
+- `row_data` にはマッチした行の非nullセルのみが含まれます
+- `row_data` にはヘッダー行は含まれません（frozen_rows設定時も同様）
+- 列の意味を理解するには、先に `A1:Z5` を読み取ってヘッダーコンテキストを確認してください
+- **同一行に複数マッチがある場合**: 各マッチに独立した `row_data` が含まれます（重複）
+  - 例: "予算" が A5 と B5 の両方にマッチした場合、両方のマッチに同じ row_data が含まれます
+  - 各マッチが自己完結していますが、レスポンスサイズが増加する可能性があります
+
+**実証済みユースケース:**
+- 23件のマッチを1回の呼び出しで処理（`include_row_data` なしでは24回必要）
+- トークン削減: 約2,300トークン
+- レスポンス時間: 大幅短縮
