(Visual FoxPro) 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.

Note: This example requires Chilkat v11.3.0 or greater.

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

* .xlsx files are Zip archives
loZip = CreateObject('Chilkat.Zip')
lnSuccess = loZip.OpenZip("qa_data/excel/fakeCompanies.xlsx")
IF (lnSuccess = 0) THEN
    ? loZip.LastErrorText
    RELEASE loZip

IF (loSheetNames.Count = 0) THEN
    ? "There are no sheets in the .xlsx"
    RELEASE loZip
    RELEASE loCsv
    RELEASE loSheetNames
    CANCEL
ENDIF

* Get the name of the 1st sheet.
lcSheetName = loSheetNames.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.
lnSuccess = loCsv.XlsxLoadSheet(loZip,lcSheetName)
IF (lnSuccess = 0) THEN
    ? loZip.LastErrorText
    RELEASE loZip

loSbCsv = CreateObject('Chilkat.StringBuilder')
loCsv.SaveToSb(loSbCsv)

* ------------------------------------------
loAi = CreateObject('Chilkat.Ai')

loAi.Provider = "openai"

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

* Choose a model.
loAi.Model = "gpt-4o"

* Add text inputs
loAi.InputAddText("Describe what is contained in the following CSV data.")
loAi.InputAddTextSb(loSbCsv)

* Ask the AI for text output.
lnSuccess = loAi.Ask("text")
IF (lnSuccess = 0) THEN
    ? loAi.LastErrorText
    RELEASE loZip
    RELEASE loCsv
    RELEASE loSheetNames
    RELEASE loSbCsv
    RELEASE loAi
    CANCEL
ENDIF

* Get the text response.
loSbResponse = CreateObject('Chilkat.StringBuilder')
loAi.GetOutputTextSb(loSbResponse)
? loSbResponse.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:
