I have a data feed that provides the linux df command as a value in my Elasticsearch database. The df output is contianed as a string in a single field. I need to display this in Canvas as a table, but can't figure out how to parse a string to a table. Since Canvas can't handle custom helper statements for handlebar.js I can't just use markdown, and I can't seem to find an expression command to parse text.
AFAIK it is not possible to do it in Canvas. I would take a look at Ingest pipelines, see this Q&A : https://discuss.elastic.co/t/ingest-pipeline-how-to-stores-the-split-values-into-separate-new-fields/200567/2
