Convert DBF to NDX

Understanding DBF and NDX file formats

DBF (Database File) is a widely used file format for storing structured data in a tabular form. It originated with dBASE and is supported by many database management systems. NDX (Index File) is an index file format used primarily by dBASE and similar systems to speed up data retrieval from DBF files by providing a sorted order for specific fields.

Why convert DBF to NDX?

Converting a DBF file to an NDX file is not a traditional data conversion, but rather the process of creating an index for a DBF database. This is essential for optimizing search and query performance in database applications that use DBF files.

How to create an NDX index from a DBF file

To generate an NDX file from a DBF file, you need database software that supports dBASE or compatible formats. The process involves specifying which field(s) you want to index. Here’s how you can do it using DBF Viewer 2000 and Clipper (for legacy systems):

• DBF Viewer 2000 (Windows):
  
  1. Open your DBF file in DBF Viewer 2000.
  2. Go to Tools → Indexes.
  3. Select Create Index and choose the field(s) to index.
  4. Choose NDX as the index type and save the file.
• Clipper (DOS/legacy):
  
  1. Open your DBF file in Clipper.
  2. Use the command: INDEX ON <fieldname> TO <filename>.NDX
  3. This will generate an NDX file for the specified field.

Best software for DBF to NDX conversion

The most reliable tools for creating NDX files from DBF databases are:

• DBF Viewer 2000 – User-friendly, supports modern Windows systems, and offers robust indexing features.
• Clipper – Suitable for legacy systems and batch processing.
• DBF Commander Professional – Another modern tool with advanced index management.

Tips for successful DBF to NDX conversion

• Always back up your DBF files before creating or modifying indexes.
• Choose the correct field(s) to index for optimal performance.
• Ensure your software supports the NDX format, as some modern tools may use CDX or MDX instead.
