Commercial Lease Data Migration: From Spreadsheets to a PMS
How to migrate commercial lease data from Excel spreadsheets into a property management system, including data preparation, mapping, and validation.
By Angel Campa, Founder · Updated March 2026 · Saves Reduces migration timeline by 60–80% vs. manual abstraction
Migrating lease data from spreadsheets or a legacy property management system to Yardi requires systematically re-abstracting every active lease to populate the new system accurately. Manual re-entry of dozens of fields per lease across a large portfolio takes months without extraction tooling.
Collect every executed lease and amendment PDF for active tenants in the portfolio being migrated.
Upload all lease PDFs to Lextract. Process each document to generate a complete 126-field abstract.
Work through the flagged fields batch by batch. Prioritize high-impact fields: rent amounts, critical dates, and option terms.
Download the full portfolio extraction as a Yardi-formatted CSV package covering all required modules: tenant, lease, charges, and options.
Import the CSV package into the new Yardi instance. Run a validation report comparing Yardi records against the Lextract abstracts to confirm accuracy before go-live.
Learn about the full integration between Lextract and Yardi Voyager, including supported export formats and critical fields.
