Switching from Tournify, Toernooi.nl or Excel? You don't need an automatic integration. Almost every tool lets you export your participants as CSV or Excel, and you import that list into Slams. This article explains how to export and which columns Slams expects.

Step 1: export your participants

In your current software, find the export or download button on your participant, member or team list and choose CSV or Excel. Working in Excel? You already have your list; save it as a CSV file.

Step 2: get the columns right

Slams expects one of these layouts per player:

  • Four columns: first name, last name, email, starting rating.
  • Three columns: name, email, starting rating.

Only a name is required; email and rating may be empty. A starting rating should be between 7.0 and 10.0; leave it blank and Slams defaults to 8.0. Both a comma and a semicolon work as a separator, so a Dutch Excel export (semicolon) is fine.

Step 3: import into Slams

In your dashboard go to Players, open the add panel and pick the CSV import tab. Upload your file. Slams dedupes automatically on email address and links existing Slams profiles, so you don't get duplicate players. More detail is in importing participants via CSV.

What about your competitions and schedules?

Slams doesn't import old schedules or brackets, and it doesn't need to: you pick a format and Slams generates a fresh schedule in two minutes. That way you start straight away with what Slams does best (ladders, leagues, ratings) instead of carrying over an old setup. Considering the move? Read switch to Slams too.
