Hostaway Reservations CSV Validator

You can, but free scripts and AI often miss edge cases that break real-world data: missing SKUs, currency formatting quirks, tax calculation errors, or date format mismatches. We have battle-tested validators specifically designed for accounting software imports that catch these issues before they corrupt your books. Plus, you get instant browser-based conversion without installing Python or managing dependencies.

Required columns are Reservation ID, Check-in, Check-out, Total Price, and Listing Name. Guest Name is also typically required.

The validator accepts standard date formats including YYYY-MM-DD and DD/MM/YYYY.

You can preview Hostaway Reservations validation results for free — no signup needed. Full validation reports use credits based on row count.

No, the maximum number of reservations in one CSV upload is 500. Split larger files into multiple batches.

Each reservation needs a unique external reservation ID. Duplicate IDs or missing IDs will cause import failures.

Phone numbers must include proper formatting with country codes. Incorrect formatting with parentheses or dashes may cause errors.

Email addresses must be valid and under 255 characters. Check for typos and proper format (name@domain.com).

Yes, both dots and commas work for decimals. Use commas for decimals and points for thousand separators if needed.

Guest first and last names are limited to 127 characters each. Longer names will cause validation errors.

Your listing ID must be a positive integer. You can find it in Hostaway under your property settings.
