Apart from designing reports, the ActiveReportsJS Designer can be used to import an existing .rdlx report (report type for ActiveReports .NET) and convert it to a .rdlx-json report. This saves the time and effort of a developer to manually replicate the layout in ActiveReportsJS. See this topic on designing reports with ActiveReportsJS Designer.
Follow these simple steps to migrate .rdlx report to .rdlx-json report:
Only reports bound to JSON and CSV data source are converted to .rdlx-json format, provided the data file is located in the same folder as report.
Data fields having a space or special characters like '&', '/', etc., which correctly appear in AR.NET preview, appear blank on ActiveReportsJS Designer preview. In that case, you need to edit the Data set query in the ActiveReportsJS Designer as follows:
1. Go to Edit Data Set.
2. Clear the query and enter it again.
3. Validate the query. Observe fields with new names are created.
4. Update the report to use new fields.
