Notes:
- Convert by referring to the master information (employee master, etc.) in the spreadsheet.
    - Example: Employee ID to Employee name / Employee name to Employee ID
    - Example: Country name to Country code / Country code to Country name
- The File ID can be obtained from the URI or the sharing settings screen.
    - docs.google.com/spreadsheets/d/{File-ID}/edit#gid=0
- The number of elements in the two ranges must be the same.
- How to specify the range depends on Google API A1 notation. (see APPENDIX)
- If multiple, each element will be string in which all cells are concatenated with spaces.
    - Example: Employee name data is stored separately in "{Firstname cell} {Lastname Cell}"
Notes-ja:
- スプレッドシートで管理しているマスター情報（社員マスタ等）を使って、データ変換できます。
    - 例：社員ID→社員の名前、社員の名前→社員ID、国名→国コード、国コード→国名
- ドキュメント ID は URL 等を参照します。
    - docs.google.com/spreadsheets/d/{File-ID}/edit#gid=0
- 2つの範囲の要素数は、同数でなければなりません。
- 範囲の指定方法は Google API の A1 notation に依ります (Appendix参照)
- 複数セルを指定した場合、「半角スペース結合された文字列」が探索対象／リターン対象となります。
    - A列に「姓」が、B列に「名」が、分けて保存されている場合、範囲指定は "A:B" と設定します。

APPENDIX-en
- A1 Notation
    - https://developers.google.com/sheets/api/guides/concepts#a1_notation
    - "Sheet1!A1:B2" refers to the first two cells in the top two rows of Sheet1.
    - "Sheet1!A:A" refers to all the cells in the first column of Sheet1.
    - "Sheet1!1:2" refers to the all the cells in the first two rows of Sheet1.
    - "Sheet1!A5:A" refers to all the cells of the first column of Sheet 1, from row 5 onward.
    - "A1:B2" refers to the first two cells in the top two rows of the first visible sheet.
    - "Sheet1" refers to all the cells in Sheet1.

- A1記法（A1 Notation）
    - https://developers.google.com/sheets/api/guides/concepts#a1_notation
    - "Sheet1!A1:B2" 「Sheet1」の上2行の先頭2セル（合計4セル）を参照します。
    - "Sheet1!A:A" 「Sheet1」のA列の全てのセルを参照します。
    - "Sheet1!1:2" 「Sheet1」の上2行にあるすべてのセルを参照します。
    - "Sheet1!A5:A" 「Sheet1」のA列5行目以降のすべてのセルを参照します。
    - "A1:B2" 最初に表示されるシートの上2行の先頭2セル（合計4セル）を参照します。
    - "Sheet1" 「Sheet1」のすべてのセルを参照します。
