speedcurve2csv converts SpeedCurve tests data to CSV. If you do not want to dabble with code, you can run analysis on your data with Excel, Google Sheets or any other spreadsheet.

Tests exported from SpeedCurve are in JSON format. A JSON file containing the tests can be piped to speedcurve2csv via stdin, or passed as the first parameter. If no output flag is specified, the CSV is sent to stdout.

speedcurve2csv can also fetch data from SpeedCurve and automate the process of collecting tests and coverting them to CSV. In this case it requires the API key from speedcurve and either the --listurls flag (to see all available URLs) or the --url flag (to get the actual tests). Note that URLs each API key refers to a different group of URLs and tests on SpeedCurve). You can save your API key with --save to avoid specyfing it at every run.

Getting Started

Install the Speedcurve2csv command line tool:

npm install -g speedcurve2csv

List all available URLs:

speedcurve2csv -k myAPIkey --save -l

And then get a set of tests:

speedcurve2csv -k myAPIkey -u URLid

Or, pass a JSON file with tests previously downloaded from SpeedCurve APIs:

Also via piping, and to a file:

cat speedcurve-url-export.json | speedcurve2csv -o speedcurve-url-export.csv


Usage: speedcurve2csv <path> [<options>]

    Path to a file containing the JSON export from a SpeedCurve URL.
    This parameter is ignored when the JSON file is being piped via stdin, e.g. cat speedcurve-export.json | speedcurve2csv

    -o, --output FILE   File path to output the results of the conversion to
    -k, --apikey API    API key from Speedcurve for the site to fetch, required for --listurls and --url
    -s, --save          Saves the API key. To clear the saved key, pass a new one with -k
    -u, --url NUM       URL id from Speedcurve of the tests to fetch
    -l, --listurls      List all URLs available from Speedcurve
    -d, --days NUM      Number of days of tests to fetch (max 365, default 7)
    -v, --version       Print speedcurve2csv version number
    -h, --help          Show this help text
