@creemer, based on further description seems like you need to edit and update a lookup file. This is a use case for KV Store where you can modify individual fields on a frequent basis. Following are couple of your options:
I mean, for example:
I had the output from this search:
index="_internal" | timechart count(ev) as cnt span=5m
And want to change some value in some cell in "cnt" column by click on it.
I click on it, then appears some modal, or popup with input, where I can write some other value for this cell, can I ?
And after changing, I want to save it to CSV...
How may I grab all the data from table, for example in array(or anything else)?
@creemer, for changing the cell value using Simple XML JS Extesion with Splunk JS Stack, please refer to Splunk Dashboard Examples app, which has couple of Examples for Table Cell Highlighting and Table Row Highlighting which access and modify cell value through TableView.BaseCellRenderer.extend
