はじめに
前回は、生成AI(ChatGPT)のAPIをコールするExcelマクロを作成するに当たり、押さえておくべき基本的なことについて説明しました。
今回は、この知識を基に実際にExcelマクロを作成していこうと思います。
マクロの構成は、前々回で説明しています。
プログラミング
標準モジュールとしてChatGPTLib CPT JsonConverterを設定します。
VBAではこんな風になるかと思います。
まずは、それぞれのプログラムを以下に示します。
標準モジュール(ChatGPTLib)
ChatGPTLib
Option Explicit
Declare PtrSafe Sub Sleep Lib "kernel32" (ByVal dwMilliseconds As Long)
Public ApiKey As String
' Create system and user messages
Public Function CreateMessages(systemContent As String, userContent As String) As Dictionary()
Dim messages(1) As Dictionary
Set messages(0) = New Dictionary
messages(0).Add "role", "system"
messages(0).Add "content", systemContent
Set messages(1) = New Dictionary
messages(1).Add "role", "user"
messages(1).Add "content", userContent
CreateMessages = messages
End Function
あるサイトからダウンロードしたソースコードです。いろいろ関数(Function)があったのですが、今回利用するもののみ抽出しています。
ChatGPT APIでは、「ロール」といって「誰目線でコメントをしているのか？」を設定することができます。この関数では「システム(system)」側の文章と「ユーザ(質問者)(user)」の文章をデータとして束ねて返却しています。

この標準モジュールには、CallGPT SetGPTmodel EscapeJSON ChatGPTの関数があります。
それぞれについてザックリ説明します。直ぐに動かしたいだけという方は、この内容を読むのを無視していただいて構いません。
| 関数名 | 概要 |
|---|---|
| CallGPT | エクセルシートの特定のセルの中に書かれた内容をChatGPTに渡す関数です。４つの関数の中で唯一Publicとなっているため、外部のモジュールなどから呼ばれる関数は唯一この関数だけです。 |
| SetGPTmodule |
ChatGPT3にするか、それともChatGPT4にするかなどを決めて設定するための関数です。選択するためのダイアログを表示させます。CallGPTで呼ばれています。 |
| EscapeJSON | 特殊文字(ここではエスケープ文字です）を変換する関数です。 |
| ChatGPT | エクセルシートのセルに書かれた内容をJSON形式に変換してChatGPT APIを呼び出しています。またレスポンスがあるまで、ある一定時間「待ち」をしています。返ってきた結果をエクセルシートのセルに表示されるようにしています。 |
また、ソースコードの先頭近くに以下のコードがあります。
Public Const ApiKey As String = "sk-proj-****************************************"
ご自身が登録した時に取得したキーを入力してください。
それから
Public Const GPT_3_MODEL = "gpt-3.5-turbo-1106"
Public Const GPT_4_MODEL = "gpt-4-1106-preview"
とあります。この記事を投稿した時には、CPT-04-mini が出ており、安くて精度の高いようですので、それに置き換えても良いかもしれません。
シート(Sheet2 | ChatGPT)
まず入力・表示をするため、シートを作成しました。
「温度」(4行目：3列目）「役割」5行目：3列目）「質問」(6行目：3列目）「回答」(7行目：3列目）という形で作りました。行と列を変えてしまうと上記でお見せしたプログラムの変更も必要となります。行と列は左記の数値に合わせていただければと思います。
また、ボタンも追加することにしました。
先ずは、「開発」タブを押下して、「デザインモード」ボタンを押下します。
これによりボタンを追加することができます。
次に「挿入」ボタンを押下し、「ActiveX」の「ボタンマーク」を押下してください。
それから、ボタンを置きたいところにカーソルを置きます。以下のようにボタンが作られます。
ボタンをダブルクリックしてください。
こんな感じになるかと思います。
そこで以下のプログラムを追加してください。
Call GPT.CallGPT
さて、ここまでできました。
では、「デザインモード」ボタンを押下して、デザインモードを解除します。これでプログラムが実行できます。
いよいよ実行
「温度」「役割」「質問」を入力してみます。下図の入力内容を参考にしてもよろしいです。
生成AIの中での「温度」とは、質問に対する回答が「一般的なもの」なのかそれとも「尖ったもの」なのかを示す数値だと思っていただけると幸いです。今回は「一般的な回答」として「0」としておきます。
また回答が誰目線にするかをせってするため「役割」に記述しました。これが先ほど出てきた「ロール」となります。
ではボタンを押下して、実行してみます。
お金をケチりたいので、「2」(gpt-3.5-turbo-1106)でやってみます。「OK」ボタンを押下します。
回答が出てきました！！
ばっちりです。後は、お好みで「温度」「役割」「質問」を入力して生成AIに問い合わせればよいかと思います。
おわりに
エクセルマクロで生成AI APIを呼び出して、セルに出力することができました。
会社や自宅でもこのマクロを用いて、いろいろ検索していただければと思います。
