QUICK ANSWER
Is it possible to convert LDB to CSV?
No - not a direct conversion.

An .ldb is a temporary lock file Access writes next to an .mdb database; it contains only computer names and Windows user names of active connections. To export real data to CSV, open the .mdb in Microsoft Access and export the desired table via External Data > Export > Text File.

Why convert LDB to CSV?

CSV is a row-and-column format for structured tabular data. An .ldb file contains exactly two fields per record (computer name and user name) and only lists whoever has the database open at that moment - not the database records you are looking for. All tables and records live in the .mdb file beside the .ldb.

Quality & what to watch

  • To export database data to CSV, open the .mdb in Microsoft Access, select a table or query, and use External Data > Export > Text File with delimited format.
  • LibreOffice Base can also open .mdb files and export tables to CSV without Microsoft Access.
  • If an .ldb is left behind after a crash, confirm no process has the .mdb open and delete it - Access recreates the .ldb cleanly on next open.

Frequently asked questions

Does the .ldb file contain my database records?
No - it contains only the computer name and Windows user name of each active connection. All records are in the .mdb file.
How do I export Access data to CSV?
Open the .mdb in Microsoft Access, select the table or query, and use External Data > Export > Text File, choosing delimited format and saving as .csv.
Why is the .ldb in the same folder as my .mdb?
Access creates it automatically when someone opens the database to manage multi-user record locking; it deletes itself when the last user closes the database.
