Overview
The Share results functionality allows you to download a copy of your metrics impact results in various formats or share via URL. This enables you to:
- Share the outcome of your experiments with colleagues without them needing to visit Split
- Keep a record of experiment outcomes in your preferred documentation formats or applications
- Conduct further manual analysis or visualisations as desired
- Import the metric results into your own internal systems
- View results in a tabular format
How to share results
When viewing the Metrics impact tab, under Results, you can find the Share results menu list on the right side of the page, above the metric cards.
To generate the results, click Share results to view the dropdown of format options. Select your chosen format and your browser starts downloading the file. A green pop up appears on the page when the file has finished downloading. Clicking on Copy URL copies a URL link to your current view in the Split application to your clipboard and doesn't download any file.
Note:
- The results reflect the version, rule, and treatments selected in the filter box above, including any metric tag or metric owner filters applied.
- Share results is not currently supported when using custom dates.
Available formats
You can generate a report containing your metrics impact results in the below formats:
CSV
- This format contains the observed metric data and the results of the statistical analyses. The report contains one row per metric and is intended to be human readable as well as appropriate for further manual analyses or reporting
- You can find reference documentation for the fields contained in the CSV reports here
JSON
- This format contains the observed metric data, the results of the statistical analyses, as well as the statistical settings and metric definitions at the time of analysis. This format is intended for ingesting data into other tools and databases
- You can find reference documentation for the fields contained in the JSON reports here
- This format presents a visual representation of your metrics impact results, similar to the Split user interface. This format is ideal for sharing results with stakeholders and for quickly understanding the high level outcomes of your tests
- An example PDF report is shown below
