Shot CSV format

Last updated: 15 October 2026

Golf Fellow imports your shots from a CSV file: one row per shot, from Trackman or any other launch monitor. You make the file, from your monitor's own export or with your own AI assistant, and Golf Fellow reads it on your phone or in your browser. We never connect to Trackman or any other service for you.

There are two kinds of file. A round file has a hole column and adds shots to a simulator round you already imported. A practice file has no holes: a range session, a practice game or a Longest Drive game. Both update the carry, side and spread of the clubs in your bag.

Rules for both files

• The first row is the header. Column names are case-insensitive; columns we don't know are ignored.
• Comma or semicolon separated. With semicolons, a comma decimal (134,5) is fine.
• An empty cell means “not measured”. Never write 0 for a value you don't have.
• The unit goes at the end of the column name: _yd or _m for distances, _ft, _yd or _m for height, _mph, _kmh or _ms for speeds, _deg for angles, _rpm for spin.
• Use one unit for all distances, and one for both speeds, in a file.
• Side values are signed: negative is left, positive is right.
• Club names can be written the usual ways: Driver, 3 Wood, 4Hybrid, 7 Iron, 7i, PW, 56Wedge, 56°.

Columns

Column	Round file	Practice file	What it is
hole	required	—	Hole number, 1 to 36
club	required	optional	Without it, the app asks you which club you hit (Driver is preselected for a drive game)
carry_yd / carry_m	required	required	Carry distance
shot	optional	optional	Shot number (drive also works in a practice file)
total_yd / total_m	optional	optional	Total distance, with roll
side_yd / side_m	optional	optional	Where the ball landed, left or right of the target line
total_side_yd / total_side_m	—	optional	Where the ball finished, left or right
ball_speed_mph	optional	optional	Ball speed (or _kmh, _ms)
club_speed_mph	optional	optional	Club head speed (or _kmh, _ms)
smash	optional	optional	Smash factor
spin_rpm	optional	optional	Spin rate
height_ft	optional	optional	Apex height (or _yd, _m)
launch_deg	optional	optional	Launch angle
attack_deg	optional	optional	Attack angle
path_deg	optional	optional	Club path
face_deg	optional	optional	Face angle
face_to_path_deg	optional	optional	Face to path

A practice file exported straight from Trackman's own table, with headers like Carry (yds) and Club Speed (mph), works as it is.

A round file

Open the simulator round in Golf Fellow and choose Add from a CSV file. Rows without a club or a carry are skipped and counted.

hole,shot,club,carry_yd,total_yd,side_yd,ball_speed_mph,club_speed_mph,smash,spin_rpm,height_ft,launch_deg,attack_deg,path_deg,face_deg,face_to_path_deg
1,1,Driver,231.0,248.2,-6.1,148.1,101.3,1.46,2450,92.0,12.1,-1.2,2.3,0.4,-1.9
1,2,7 Iron,152.4,158.0,4.2,118.0,84.2,1.40,6100,88.5,17.8,-4.0,-1.1,0.6,1.7
2,1,Driver,224.5,240.1,12.0,146.0,100.1,1.46,2500,90.1,11.8,-0.8,3.0,2.2,-0.8

A practice file

Import it as Simulator practice: share the file to Golf Fellow on your phone, or choose it in the browser. Put the date in the file name (longest_drive_2026-10-14.csv) and the session is dated that day, so your club history shows it in the right place.

drive,carry_yd,total_yd,side_yd,total_side_yd,ball_speed_mph,club_speed_mph,smash,spin_rpm,height_ft,launch_deg,attack_deg,path_deg,face_deg,face_to_path_deg
1,206.5,229.1,16.5,22.0,129.4,94.2,1.37,3072,80.2,15.6,3.2,-11.5,-1.8,9.7
2,160.1,199.8,-31.3,-42.3,118.7,,1.37,976,40.0,14.7,,-12.5,-6.6,5.9
3,192.4,228.4,9.6,13.5,127.2,89.6,1.42,1456,53.5,14.6,3.9,-8.6,0.4,9.1

With several clubs in one session, add a club column and every row is filed under its own club.

Ask your AI assistant

If you use an assistant (Claude or similar) that can read your Trackman or launch-monitor data, paste this:

Make a CSV of my shots for Golf Fellow, following https://golffellow.app/csv exactly.
One row per shot. Use these column names:
hole,shot,club,carry_yd,total_yd,side_yd,total_side_yd,ball_speed_mph,club_speed_mph,smash,spin_rpm,height_ft,launch_deg,attack_deg,path_deg,face_deg,face_to_path_deg
- Leave out "hole" for a practice session or a game; include it for a round.
- Side values are negative for left.
- Leave a cell empty when there is no value. Never write 0 for a missing value.
- Use yards, feet and mph throughout (or metres and km/h, but not mixed).
- Name the file after what it is and the date, e.g. range_2026-10-14.csv.

If the import says no

• “No hole” on a round: every row needs a whole-number hole from 1 to 36.
• Missing columns: a round needs hole, club and a carry column; a practice file needs a carry column.
• Mixed units: don't mix _yd and _m, or two speed units, in one file.
• Anything else: email hi@golffellow.app with the file and we'll look.
