Your inventory manager just discovered 47 products have the wrong supplier code. Manual fixes? Two hours of tedious clicks and typos. Batch Field Updater lets her select all 47, preview the change, and commit in under 90 seconds—with a one-click undo if something looks off. Works on any Odoo model: products, partners, sales orders, invoices. Preview shows exactly what will change before you commit. Validation catches conflicts and required fields before they break workflows. Undo reverses the last batch if you spot an error after saving. Data teams report saving 4-6 hours per week on routine corrections and imports. Stop clicking through forms one by one.
