@phildunlap Hi Thanks for your response. I am a beginner for Mango. I am sorry for my unclear questions.
I am trying to create data values by importing the CSV file. According to your suggestion, I changed to /dataImport.shtm page to import CSV file. But, the page warns me that Number of headers is invalid. Expected 29 but 8. Do you know how to solve this problem? Also, in the file type selection, I only find CSV and Excel types are available to be imported to Mango. How to import a JSON file in /dataImport.shtm page? My Mango version is 2.8.6. Thanks so much for your help!!
Hi Thanks for your response. I am using Import/Export function to import a CSV file. But this function did not create a data source automatically for me. After clicking import, it just shows me Invalid XID Reference. Could you just briefly explain to me the steps to successfully import a CSV file to Mango?
I tried to use Configuration Import function to import a CSV file, but the message blocks shown Invalid XID Reference. I think this problem may be caused by no data source were created for these Export ID. I do not know how to build a data source and use it to contact to the CSV file. Could anyone who know this problem teaching me how to import CSV file into Mango Automation. I greatly appreciate for your help.
