Free online LST to CSV converter

Database tools may save query results or record listings as LST files, while spreadsheet and database import workflows often accept CSV instead. Converting the listing makes its rows easier to inspect, edit, or load into another system.

What the LST format is

.lst is not a single standardized database interchange format. In database workflows, it can identify a text listing or report generated by a database program; the contents may be delimited rows, fixed-width columns, or formatted report text. The creating program and the file’s contents determine how its fields are arranged.

What the CSV format is

CSV stores tabular data as text: each line represents a row, and a separator divides fields. Commas are common, but applications can also use other separators. CSV is supported by spreadsheet software and many database import tools, making it useful for transferring records between programs.

How to convert LST to CSV

Online on 101convert.com

1. Upload the LST file on the converter page. Multiple files can be added for batch conversion; the page shows the per-file size limit.
2. Before converting, choose the column separator and character encoding that match the LST file.
3. Convert the file, then download the CSV output.

Offline with desktop software

LibreOffice Calc (Windows, macOS, and Linux) can convert an LST file when its contents are text arranged in consistently separated columns:

1. Open the file using File → Open. If it is not listed, select the option to show all files.
2. In the text import dialog, select the correct character set and separator, then check that the preview places each field in its own column. Choose fixed-width parsing instead if the data uses aligned columns.
3. Use File → Save As, choose Text CSV (.csv) as the file type, and confirm the CSV export settings.

Microsoft Excel (Windows and macOS) can also import tabular text: use Data → From Text/CSV, select the LST file, set the delimiter and encoding, and load the previewed data. Then use File → Save As and choose CSV.

Quality and compatibility

Check the LST structure before conversion: report headings, page breaks, totals, or inconsistent spacing may be imported as data rather than clean records. If columns are fixed-width or the file contains formatted report text, identify the field boundaries or extract the records before saving as CSV; changing the extension alone does not convert the layout.

Verify the output’s separator, character encoding, and row and column counts. CSV does not preserve database types or formatting, so check dates, decimal separators, and identifiers with leading zeros after import.
