Importer · CSV or XLSX

Leaving a tracker that went paid? Bring your growth measurements.

Export what you can from your old app or spreadsheet, drop the file here, match the columns, and every weight, length and head circumference lands on the right WHO or CDC curve in a free, private record.

  • Any CSV or Excel file with a date column and at least one of weight, length/height or head circumference.
  • Units detected for you: kg, grams, lb, lb + oz, cm, mm or inches. Decimal commas are fine.
  • A preview before anything is saved, and a “check this number” step for values far outside the reference range.
  • Free, no ads, export any time. Your data is never sold or shared.

What childow is, and isn’t

childow is a growth and development record: measurements on the right charts, CDC milestone checklists, checkup reports and a family circle. It is not a feed, sleep or diaper tracker, so those columns are left out of the import. If you need feed logging, keep a tracker for that and bring the growth history here.

We don’t promise support for any particular app’s export file. If your file has a date column and growth columns, the mapper can read it; if it can’t, tell us what the columns look like.
