Video: Export data from PostgreSQL query result to Excel file in a few clicks

This video shows how to export data from PostgreSQL query result to Excel file in a few clicks with Withdata DBToFile, or with the free Export PostgreSQL query result to Excel online tool. It covers the postgres query side and the Excel side.

Export a PostgreSQL query result to Excel: what this does

This shows how to export the result of a PostgreSQL SELECT — a filtered, joined or aggregated result — to an Excel workbook, rather than dumping a whole table. The video above is the full flow.

Steps

Open Withdata DBToFile and connect to PostgreSQL (host, port, database, user).
Switch to Query and paste the SELECT you want to export.
Choose Excel as the destination format.
Pick the output workbook and click Export.
Save the session so the same query can be re-run later.

Query vs whole table

Exporting a query instead of a table lets you shape the data before it reaches the spreadsheet: select only the columns you need, filter rows, join several tables and aggregate. That keeps the workbook small and the headers meaningful.

PostgreSQL query to Excel: details worth knowing

Alias duplicate columns. A join can produce two columns named id; use AS so each spreadsheet header is unique.
Numbers. numeric/decimal keep their scale; bigint above 2^53 can lose precision if a reader treats it as a double.
Dates and timestamps. timestamp/timestamptz become spreadsheet datetimes; format the column if you only want the date.
Booleans and NULL. boolean becomes TRUE/FALSE; NULL is left as an empty cell, distinct from an empty string.
jsonb and arrays. They are written as text; use jsonb_array_elements or unnest in the query to flatten them into columns.

FAQ

Can I use parameters in the query?: Yes — a saved session can include the query with parameters or a filter you edit each run.
Does it need a PostgreSQL client?: No; the tool connects directly to PostgreSQL.
Can it run on a schedule?: Yes; call the saved session from the command line or a scheduled task.
