currently we use a process to upload data to quickbase through the import "from the clipboard" feature. This has worked great for us. Is there a way to import from the clipboard to update existing data without adding new?
I will answer this just to close it out. As you discovered, if you upload the RECORD ID or the Key field it will update existing records. Be careful not to upload blanks into any extra fields, as they will be updated to blank. ie don't assume that uploading a blank would not affect the field, it will!
