Sample file comparing various methods of creating JSON from large record sets. This is an older 16 compatible file which only exports 5 fields. The 17 compatible demo I showed was rather a mess as a result of incomplete changes to support 17 and the 10 field sample data. I'm more than happy to answer any questions or queries. This demo was originally produced as part of the FileMaker community discussion at https://community.filemaker.com/thread/184130
