About NDX files

The .NDX extension most commonly identifies a Database Index file utilized by HFSQL (formerly HyperFileSQL) from PC SOFT or legacy dBASE systems. These files serve as a lookup map to speed up sorting and searching within a larger database, accompanying primary data files like FIC or DBF.

A key problem with .NDX files is that they are structurally useless on their own; they contain pointers rather than readable content. Users often encounter friction when attempting to "open" these files, only to find unreadable binary code or metadata because the actual data resides in a sibling file. Furthermore, older Neat scanner software used this extension for document archives, creating confusion for users trying to recover scanned receipts without the discontinued software.

For database users, the solution is not converting the index, but exporting the primary database file to CSV, SQL, or Excel formats using the original database engine. However, if your file is a Neat archive, it may be a disguised compressed folder; converting it to ZIP or extracting it to PDF and JPG allows you to recover your documents for archiving and easy web viewing.

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

Users also converted FIC, MMO, DBF, CSV, IDX, PDF, RVT, DB, LBL and STR files.
