About NDP files

The .NDP extension is most frequently a proprietary project file used by Greenbrier Graphics Net Deed Plotter to store land survey data, though it also serves as a specialized payroll format for Banco de Chile transactions.

For real estate professionals and surveyors, the Net Deed Plotter file contains critical metes and bounds descriptions used to generate property maps. A common problem here is the proprietary lock-in: these files are essentially small databases of vector instructions that standard CAD software like AutoCAD or GIS tools cannot read natively. If you receive an .NDP file from a title company or surveyor but lack the paid Net Deed Plotter license, the data is inaccessible. To make this data usable for clients or archiving, the best approach is converting the visual plot to PDF or a raster image like PNG for easy viewing, or extracting the text description to TXT.

In the context of Chilean finance, .NDP files act as 'Nómina de Pagos' (Payment Payroll) containers used to process bulk transfers via Previred or Banco de Chile. These are typically rigid, fixed-width text files designed for machine processing rather than human reading. Attempting to edit these manually in a text editor often breaks the strict formatting required for bank validation. Converting these files to CSV or XLSX allows accountants to audit the payroll data in spreadsheet software without risking file corruption.

Convert.Guru analyzes your NDP file, detects the exact format, and lets you read the text inside.

Users also converted NDB, ZIP, NPF, NPI, NDC and GNP files.
