About this tool
Turn an Apple Health export into readable charts on your own device.
The Apple Health Export Explorer reads the <Record> elements out of an Apple Health export.xml and summarizes them by data type — count, unit, mean, minimum and maximum for each — so you can see what is actually inside a multi-hundred-megabyte export without opening it in a spreadsheet. It strips the HKQuantityTypeIdentifier / HKCategoryTypeIdentifier prefix so types read as StepCount or HeartRate rather than raw keys, and it processes up to 50,000 records per run (5,000 by default). It runs on text you paste, so the export never leaves your device.
Open Apple Health Export Explorer on AltFTool — it loads instantly in your browser.
Paste your Apple Health export.xml text into the 'Apple Health export.xml content or Record lines' box, or load the 'Two records' example.
Set 'Maximum records to summarize' — the default is 5,000 and the field accepts up to 50,000 Record elements.
Read the Type / Count / Unit / Mean / Min / Max table, then use Copy or Download to save it as apple-health-export-explorer.txt.
Records are grouped by health type with count, unit, mean to four decimal places, and min/max, sorted with the most numerous type first.
The HK…Identifier prefix is stripped automatically, so HKQuantityTypeIdentifierHeartRate is shown simply as HeartRate.
It scans for <Record …/> elements anywhere in the text, so a fragment copied out of a huge export works as well as a whole file section.
Up to 50,000 Record elements per run, with a default limit of 5,000. Records past the limit are ignored rather than truncating the file, so raise the limit if the count reported back is lower than you expected.
In the Health app on iPhone, open your profile and choose the option to export all health data; iOS produces a zip archive containing export.xml. Unzip it, open export.xml in a text editor, and paste the section you want to inspect.
Only <Record> elements and their attributes are read. Nested workout and route data, clinical records, provenance and device metadata, and timezone semantics are not parsed, so the mean and range are simple statistics over the value attribute, not clinically adjusted figures.
No — it reports what your file contains and nothing more. The mean, min and max are arithmetic summaries of raw sensor values, with no interpretation of context, accuracy or health meaning; discuss anything concerning with a clinician who can see the full picture.
