Tracking Playtime Without Losing Your Mind
I spent about three hours last week debugging a spreadsheet that was supposed to auto-sync my Steam Deck library with a Google Sheet. It didn't work because the API rate limits are real and they will punish you if you don't handle backoff correctly. That detour led me to use a simpler approach, and I've stuck with it ever since. The core idea is straightforward enough that you can build your own version in a weekend. At its most basic, a Daily Steam Deck Worksheet is a structured log where you record which games you played each day, how long you played them, and occasionally some notes about performance or whether the game actually runs well on the hardware. It can be as simple as a Google Sheet with columns for date, game title, hours played, and a rating out of five. More elaborate versions pull data from Steam's web API automatically and populate cells without manual entry. The manual version is easier to maintain and less likely to break when Steam changes something on their end. I built mine using Google Sheets with a combination of manual entry and an Apps Script that pulls my library list once per week. The script runs every Sunday at 2 AM and refreshes a table of installed games with their last-played timestamps. From there, I just fill in the daily hours. The whole setup takes maybe five minutes a day to maintain and about ten minutes a week for the automated piece.
How to Set Up a Manual Version
If you just want something working today, here is the fastest path. Open a blank Google Sheet and create these columns in the top row: Date, Game, Session Start, Session End, Total Hours, Play Mode (Handheld/Tabletop/TV), and Notes. That is it. Every time you finish a gaming session, log it. Do not overthink the categories. The goal is pattern recognition, not scientific precision. Use data validation on the Play Mode column to create a dropdown. Use conditional formatting to highlight any row where Total Hours exceeds four, since that is about when the Deck's battery starts feeling like a suggestion rather than a guarantee. Add a pivot table at the bottom of the sheet that summarizes total hours by game and by week. This pivot table will eventually tell you which games you keep coming back to and which ones you installed and never touched again.
How to Set Up an Automated Version
The automated approach uses Steam's community API endpoints. You will need your Steam ID, which you can find by going to any Steam community page and looking at the URL, or by using a site like steamid.io to resolve your custom URL. The endpoint you need is the owned games list, which returns JSON containing every game in your library along with playtime figures. Here is the script I actually use. It is not elegant but it works reliably:
Get the Full Details
function fetchSteamLibrary() {
var steamId = "YOUR_STEAM_ID_HERE";
var apiKey = "YOUR_STEAM_WEB_API_KEY";
var url = "https://api.steampowered.com/IPlayerService/GetOwnedGames/v0001/?steamid=" + steamId + "&key=" + apiKey + "&format=json&include_played_free_games=true";
var response = UrlFetchApp.fetch(url);
var data = JSON.parse(response.getContentText());
var games = data.response.games;
var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Library");
sheet.clearContents();
sheet.appendRow(["Game Name", "App ID", "Playtime Hours", "Last Played"]);
games.forEach(function(game) {
var name = game.name;
var appid = game.appid;
var hours = Math.round(game.playtime_forever / 60);
var lastPlayed = game.last_played ? new Date(game.last_played * 1000).toLocaleDateString() : "Never";
sheet.appendRow([name, appid, hours, lastPlayed]);
});
}
Paste this into Extensions > Apps Script in a Google Sheet, replace the two placeholder values with your own data, and set up a weekly trigger under Edit > Current project's triggers. The first run will populate your library sheet. After that, it refreshes it automatically. You still log daily play sessions in a separate sheet, but the game list stays current without manual updating. I discovered a caveat after running this for about two months. Steam's API does not return playtime for free-to-play games unless they were added to your library after a certain date. Games like Dota 2, Team Fortress 2, and Path of Exile showed zero playtime in the data even though I had logged hundreds of hours. The workaround is to check the box labeled "Include free games" in the API request parameters, which forces Steam to include them. It was not documented clearly anywhere and I found out through trial and error.
What the Data Actually Shows You
A properly maintained log becomes useful around month two. That is when patterns emerge that you would not notice otherwise. You will see which games you start and abandon within a week. You will see that certain titles consume forty percent of your total gaming time but only twenty percent of your enjoyment score. You will identify which games are worth revisiting during a long weekend versus which ones are fine to skip entirely. The play mode column is where most people waste an opportunity. Tracking whether you played in handheld, tabletop, or TV mode reveals a lot about your actual usage patterns. I found that I was spending roughly sixty percent of my time in handheld mode but only about twenty-five percent of my gaming sessions were short enough to benefit from portable play. In other words, I was carrying the Deck around hoping I would play it but mostly not using it as intended. That realization alone was worth the effort of building the worksheet.
Edge Case: Games That Steam Does Not Track Properly
Some games launch through third-party platforms like GOG Galaxy, Epic, or Ubisoft Connect. Steam sees them as non-Steam shortcuts and will not report accurate playtime. The Deck's native overlay sometimes catches these sessions, but not consistently. For those titles, manual entry is the only option. I keep a small subsection in my sheet called "External Launchers" and log those games separately rather than trying to force them into the automated pipeline. Another edge case I ran into involves games that crash or require a restart mid-session. If you close the Deck and reopen it, Steam may count the second sitting as a separate session even though it is the same gaming block. The solution is to log sessions by date rather than by discrete play periods. My current method uses one row per calendar day per game, with total accumulated hours for that day. This avoids the double-counting problem entirely.
Limitations You Should Know About
No worksheet solves every problem. The automated approach depends on Steam's API staying stable, and they have changed it before without much warning. The manual approach depends on your consistency, and consistency drops off quickly after the initial novelty wears thin. Most people abandon their log within three weeks. If you know that is you, stick to the simpler version with fewer columns. A sheet with six columns that you actually fill out is better than a sheet with sixteen columns that collects digital dust. There is also the matter of data privacy. Storing your Steam ID and API key in a Google Sheet means that data lives on Google's infrastructure. It is not sensitive information in the traditional sense, but if you share the sheet or publish it publicly, anyone with the link can see your library and play patterns. Keep the sheet private or use a copy for public sharing that strips identifying information. If you want a no-setup alternative, consider Steam's built-in playtime tracking combined with third-party sites like HowLongToBeat or SteamDB. These do not give you the daily granularity that a worksheet provides, but they require zero maintenance and show you how your playtime compares to average completion times. That comparison data can be surprisingly motivating for finishing games you have left sitting in your library.
Building Something That Sticks
The best worksheet is the one you actually use. Start simple. Add complexity only when you hit a limitation that the current version cannot address. Review your data monthly and delete columns that nobody looks at. A lean log that captures the essentials beats a comprehensive system that you stop maintaining after a few weeks. The goal is visibility into your habits, not creating another admin task that competes with the thing you actually wanted to do, which is playing games. My current setup has been running for eight months with minimal changes. I log about two dozen games total across the sheet, which covers roughly ninety percent of my actual playtime. The remaining ten percent goes into the External Launchers section. The weekly automation runs without issues, and the monthly review takes about three minutes. That is the target. Anything more than that and you are optimizing the wrong thing.
