Thanks Ted and Dave for the reponses! It turns out that in my current case the DataToClip approach works perfectly. I was totally surprised that it could be so simple. (I was using copy to type XL5 when I wrote to a file so I expected I would need to pass that detail to DataToClip. I guess the clipboard only cares about the values.) Doing it this way eliminates the need to create a file, upload the file to Google Drive, and find and import that file to Sheets

If I get into a situation where I need a more elegant solution I can consider ODBC or Chilkat.

Thanks again - Joe

Joe, Data2Clip is a possibility but beware that the data transformation from VFP to Spreadsheet can be unpredictable and not result in a data type you expect.

Are you uploading the data in Sheet format or in an intermediate FORMAT LIKE csv?

I would do as Ted suggests and look at external sources. Personally, I use Chilkat Software a lot and there is an interface directly into Google Sheets

I have VFP code that combines multiple events recorded on a phone app into a single Timeline table. The final step in the code is to copy to type XL5. Each time the code is run to include new data, the output file is written with the same name

I opened the resulting file in Google sheets with the data in the first tab called DATA. Subsequent tabs query the DATA tab to produce charts with various combinations of events for various time frames. The charts can be exported as PDFs for external use.

My issue is figuring out the best way to update the data in the Sheets file as new data is available. Here are some considerations and ideas:

· Each time I upload the data file to Google Drive the same filename is assigned to a different file (all with the same name.) The only way I have found to determine which is the authority is to look at the last modified time. This seems like an invitation to user errors. Perhaps there is a configuration change to avoid this behavior.

· Sheets has the capability to query data from an unopened table if its URL is specified in the query. Wiping and reimporting the data appears to be a workable approach but it requires finding the correct file to import to the DATA sheet with the specified URL used to hold the data,

· Another possibility might be to open the table from VFP in Sheets and record the URL on the clipboard and then open the Sheets file containing the chart specs and update the URL in the query.

· Another might be to copy the data to the clipboard and then paste it into a DATA tab on the Charts sheet.

· Finally, I’m wondering if there is a way to write the data onto the clipboard from VFP and then paste it directly into the Sheets Chart sheet. This would eliminate the nuisance of uploads and filename confusion.

· A pure VFP approach would eliminate the need for data transfer, but I chose the Google approach because I am new to charts and because I wanted to learn about Google’s capabilities.

Any suggestions welcome!

Thanks in advance - Joe
