Misc Thoughts, Excel and SPARQLI often end up running a big SPARQL query (usually on a server), exporting the results a TSV, and post processing the results with some combination of vi, perl, awk, sort etc., then loading the processed data into a copy of Excel to get stats out of it, or produce a chart or whatever.
