in reply to perl copy multiple worksheets

You can use Spreadsheet::ParseExcel to read .xls files and Spreadsheet::WriteExcel to create your merged file.

You may need to take care of formatting and the like. If your data set is large you may need to look at Spreadsheet::WriteExcel::Big.

[Corion]: Meh. I have a very simple mechanism to scrape+track prices, and even to send me mail if something changes (via cron), but SQLite doesn't support window functions, so my simple SQL to determine a price change won't work :-( Maybe I should store the DB ...
[Corion]: ... in Pg, but that would mean that I'd have to deal with credentials and stuff :)
[Corion]: In fact, the whole thing is just four simple programs, one App::scrape, another being DBIx::RunSQL, and one some glue to convert a JSON object into an SQL INSERT statement (+DBI connect/execute), so it would be an incredibly simple solution...
[Corion]: ... but that simplicity falls down due to SQLite letting me down and me being too lazy to move to a real DB. Maybe DBD::CSV can handle window functions...
[hippo]: Pg has the "trust" mechanism if you don't fancy using credentials for a trivial db.
[Corion]: hippo: Oooh, that sounds quite nice - let me read the documentation on that :)
[hippo]: https://www. postgresql.org/ docs/current/ static/auth- methods.html#AUTH- TRUST
[erix]: or compile & run an instance as yourself (not user 'postgres')
