Add Steps to Garmin Connect Manually, Free CSV Tool

Fill your missing days
in Garmin Connect

Wearable Converter leaves the last 3 days out of every Fitbit and Google Health conversion, because those days may not have finished syncing to Google's servers when you exported. Your app still has the real numbers though. Read them off the screen, type them in below, and download a CSV ready to drag into Garmin Connect. Works for any blank day, not just the last 3. No account, no sign-up, runs entirely in your browser.

How to import
into Garmin Connect

The whole process takes under two minutes. Here's exactly what to do, starting with where the numbers come from.

Grab the numbers from your app

Open the Fitbit or Google Health app on your phone and tap into each day you're filling. The app keeps your recent days locally even when they haven't synced to Google's servers yet, which is exactly why they were missing from your export. Copy across the steps, calories burned, distance, floors, and active minutes for each day.

Wait for the day to end: only enter a day once it's over. Today's totals keep moving until midnight, and Garmin silently drops any date that's in the future, so this tool blocks future dates and warns you if you enter today.

Fill in up to 3 days and download

Enter the date and the numbers for each day, then hit Download Garmin CSV. One filled day is enough, leave the others blank and they're skipped. The file saves instantly. Nothing is sent to a server. It all runs locally in your browser.

Missing a field? Steps or calories is enough for a valid row. Floors and active minutes are optional, and columns your app doesn't show (like the old sedentary minutes split) are filled with zeros automatically, which Garmin accepts.

Open the Garmin Connect import page

Go to connect.garmin.com/modern/import-data in your browser and log in. This is Garmin's official import page. You must use the web browser version; the Garmin Connect mobile app doesn't support CSV imports.

Drag the file in and set the import options

Drag your downloaded file onto the upload area. Garmin shows an "Import Fitbit Data" screen with a few dropdowns. Set Date Format to the day-first option (shown as 31-12-2026 style), and Length Units to match the KM or Miles toggle you used in the tool. Click Continue.

Getting "An error occurred with your upload"? This is a known Garmin bug that affects all CSV imports, not a problem with your file. Try the same file again, it usually succeeds on the second or third attempt.

Check the days in Health Stats

After the import, go to Health Stats → Steps in Garmin Connect. The filled days should appear on their correct dates within a few minutes, along with calories, distance and floors on their respective pages.

A day not appearing? If your Garmin watch already recorded anything for that day, Garmin keeps its own data and ignores the imported row. That's expected behaviour, imports only land on days Garmin has nothing for.

FAQ

Does this tool store my data?

No. Everything runs in your browser. The numbers you type are used to build the CSV file locally and are never sent to any server. Close the tab and the data is gone.

Can't I just type steps into Garmin Connect directly?

No. Garmin Connect has no manual entry for steps, calories, distance or floors. Weight is the only daily metric you can key in by hand. A CSV import is the only way to place activity numbers on a past date, which is exactly what this tool builds for you.

What happens if Garmin already has data for that day?

Garmin gives its own data precedence. If your Garmin watch (or a previous import) already recorded a day, the imported row for that day is ignored and your existing data stays untouched. Blank days import normally. So you can't overwrite or double-count a day by accident, but it also means this tool only works for days Garmin has nothing for.

Where do I find the numbers to enter?

In your Fitbit or Google Health app. The app keeps your most recent days on the phone even when they haven't finished syncing to Google's servers, which is the very reason a Takeout export can be missing them. Open the day in the app's history view and copy across what you see: steps, calories burned, distance, floors, and active minutes.

Why is there only one active minutes field?

Old Fitbit exports split minutes four ways: sedentary, lightly, fairly and very active. The current app shows a single Active Zone Minutes number instead, so that's what this tool asks for. The number you enter is written to the Very Active column, which Garmin turns into Intensity Minutes. The other minute columns are filled with zeros, which Garmin accepts.

Will imported days count toward Garmin badges and challenges?

No. Imported data never counts toward badges, challenges or streak awards in Garmin Connect. It does appear in your step totals, graphs and Health Stats, which is what matters for keeping your history complete.

Can I add more than 3 days?

Run the tool as many times as you need. Each download holds up to 3 days, and you can import as many files as you like, one at a time. If you're trying to move months or years of history, that's what Wearable Converter itself is for: it converts your entire Fitbit or Google Health export in one pass for $19.

What date format does the file use?

The file always uses DD-MM-YYYY, day first, regardless of which format you chose for typing dates into the tool. When Garmin's import screen asks for a date format, pick the day-first option (shown as 31-12-2026 style) and the import will line up correctly.
