XLSX Spreadsheet in AI Query

See more AI Examples

This example shows how to convert a .xlsx spreadsheet to CSV text for input in an AI query. Currently, most AIs can't handle Excel file inputs directly. If the spreadsheet is small, you can convert it to CSV text and use it as a text input. VB.NET

Dim success As Boolean = False

' This example assumes the Chilkat API to have been previously unlocked.
' See Global Unlock Sample for sample code.

' .xlsx files are Zip archives
Dim zip As New Chilkat.Zip
success = zip.OpenZip("qa_data/excel/fakeCompanies.xlsx")
If (success = False) Then
    Debug.WriteLine(zip.LastErrorText)
    Exit Sub
End If


Dim csv As New Chilkat.Csv
Dim sheetNames As New Chilkat.StringTable
success = csv.XlsxGetSheets(zip,sheetNames)
If (success = False) Then
    Debug.WriteLine(csv.LastErrorText)
    Exit Sub
End If


If (sheetNames.Count = 0) Then
    Debug.WriteLine("There are no sheets in the .xlsx")
    Exit Sub
End If


' Get the name of the 1st sheet.
Dim sheetName As String = sheetNames.StringAt(0)

' Load the 1st sheet into the CSV.
' We could've also loaded the 1st sheet by passing an empty string for the sheet name.
success = csv.XlsxLoadSheet(zip,sheetName)
If (success = False) Then
    Debug.WriteLine(zip.LastErrorText)
    Exit Sub
End If


Dim sbCsv As New Chilkat.StringBuilder
csv.SaveToSb(sbCsv)

' ------------------------------------------
Dim ai As New Chilkat.Ai

ai.Provider = "openai"

' Use your provider's API key.
ai.ApiKey = "MY_API_KEY"

' Choose a model.
ai.Model = "gpt-4o"

' Add text inputs
ai.InputAddText("Describe what is contained in the following CSV data.")
ai.InputAddTextSb(sbCsv)

' Ask the AI for text output.
success = ai.Ask("text")
If (success = False) Then
    Debug.WriteLine(ai.LastErrorText)
    Exit Sub
End If


' Get the text response.
Dim sbResponse As New Chilkat.StringBuilder
ai.GetOutputTextSb(sbResponse)
Debug.WriteLine(sbResponse.GetAsString())

' Sample output:

' The CSV data contains information about five companies, including the following fields:
' 
' 1. **CompanyName**: The name of the company.
' 2. **Address**: The street address of the company.
' 3. **City**: The city where the company is located.
' 4. **State**: The state where the company is located, abbreviated.
' 5. **Zip**: The ZIP code for the company's location.
' 6. **Phone**: The phone number of the company.
' 
' Each row in the dataset corresponds to a different company with details provided for each of these fields:
