How to import one or more log archives into Google Sheets for additional analysis and charting.
In Google Sheets, choose Start a new spreadsheet > Blank. Upload the archive file and let Sheets auto-detect settings:
After importing data, rename column headers to more useful names (from Permanent log archives).
To analyze a subset of logs, use Data > Filter. See filtering.
As of this writing, Google Sheets are restricted to 2 million cells (more).
