Export data and Import data with Salesforce DX (SFDX)
У вашего броузера проблема в совместимости с HTML5
If you have to get data from one Salesforce Org to another Salesforce Org, this is how you do it. Be sure to install Salesforce DX (SFDX) because you'll need to use the SFDX command line interface to pull this off.
In this example, we export data as follows:
sfdx force:data:tree:export -q ./soql/Candidate.soql -u DataTest -p -d ./data
We import the data as follows:
sfdx force:data:tree:import -p ./data/PLANFILE.json -u DataTestIn
Look for the example files on Github!
