Export PostgreSQL tables into a new Excel workbook, one sheet per table. Numbers arrive as numbers, and dates as real Excel dates.

Reads the tables of a PostgreSQL database.
Writes an .xlsx workbook. No Microsoft Office or Excel driver is needed.
Runs on Windows as a desktop application.
The same download loads Excel into PostgreSQL. One licence key covers the MySQL and SQL Server pairs too.

What the workbook looks like

One sheet per table

Each sheet is named after its table. A name Excel cannot take, such as one over 31 characters, one with [ ] : * ? / \, or a duplicate, is changed to a valid one.

Column names in the first row

The rows follow underneath. A workbook holds tables, columns, and rows only.

A new file on every run

A workbook already at that path is replaced, and the application warns you before the run. Sheets are not added to an existing workbook.

A job keeps both connections, the table selection, and the options. Run it again from the application, or by name from Task Scheduler with --run-job.

How PostgreSQL values arrive in Excel

Scroll sideways to see all columns.

In PostgreSQL	In the workbook	What needs attention
Numbers	Numbers.	Excel keeps 15 significant digits. A longer number is written as text, every digit kept.
Dates and date-times	Excel dates, with a date format applied.
Text	Text.	Excel holds 32,767 characters per cell. A longer value is refused by name, not cut.
Booleans	`TRUE` and `FALSE`.
NULL	An empty cell.

Excel's row limit, and what stays in PostgreSQL

A sheet holds 1,048,575 data rows. A larger table is refused by name, never cut short. Keys, indexes, and constraints stay in PostgreSQL: a workbook has no place for them.

How to migrate PostgreSQL to Excel

Setup: connect PostgreSQL and Excel

Choose the source and destination connections side by side on one screen. A connection is saved once and reused by every job.

PostgreSQL source

Use the PostgreSQL connection guide.

Excel target

Name the .xlsx file to write. A workbook already at that path is replaced; the application warns before the run.

Tables & mapping: see every Excel type before a row moves

Pick the tables, then open one: each PostgreSQL column shows the Excel type it becomes. Change a type or a name in place; the line at the bottom names anything that would fail.

Execution: start it, and the job is saved

Review what the run will do, start it, and read the log as it goes. The job stays in the list to run again or put on a schedule.

Verify the copy

With Verify after the run on, the destination is checked when the copy ends: schema, totals and rows. The window shows which tables, rows and columns differ.
