What it does

Upload a property listing export from an MLS, Zillow, Redfin, or internal spreadsheet. Get back a clean, normalized CSV with consistent address formatting, price fields as plain numbers, dates in ISO format, and square footage as integers — ready to import into a CRM, database, or reporting tool.

The problem it solves

MLS exports are notoriously messy: prices formatted as "$1,250,000", square footage as "1,850 sqft", list dates in mixed formats, and addresses that vary between full street names and abbreviations. Loading raw MLS exports into a CRM or running analysis requires significant cleanup first.

What it handles automatically

  • Price cleaning — Strips $, commas, and "USD" from price fields; converts to plain decimals
  • Square footage — Removes "sqft", "sq ft", and similar suffixes; returns integer values
  • Address normalization — Consistent abbreviation expansion and proper case
  • Date standardization — Converts list date, under-contract date, and close date to ISO 8601
  • Status normalization — Maps "Active", "ACT", "A" and similar variants to a standard status set

FAQ

Does it work with the export format from my MLS? The tool uses a flexible column mapping step. As long as your export is a CSV or XLSX, you can map your columns to the standard fields.

Does it validate listing data against MLS records? No — this is a formatting tool only. It normalizes what's in your file; it doesn't make external API calls.

Does it store my data? No. All processing is in your browser.
