How to read data from multiple Excel files with Informatica

Question

I have data in multiple Excel files and all my Excel files are placed in the same folder. I want to read data from multiple Excel files and load the data into a Oracle destination table. How can I achieve this using Informatica PowerCenter?

This is a very similar example done using SSIS .

Answer 1

Please share the details of which OS your Powercenter client is installed and also the version of informatica..?

This is possible however a bit tricky..

Answer 2

There are multiple ways to achieve the same result. You have only mentioned the client OS.... not the server OS.

Since your Q is very vague... i'll post it for Win OS.

From my experience, I would say, select the "indirect load" . Create a new text file and list all the excel files which you want to load.

Answer 3

The easiest and hassle free way is to convert the excels to csv files.

If your Informatica server is installed in windows, it is recommended to use a VB/powershell script to convert the file to CSV and then use indirect file load. If the informatica server is installed in linux then you have to use a perl script to convert the file to csv. Reading multiple excel files directly is a very cumbersome effort and will have a lot of challenges.

Answer 4

Informatica uses ODBC to read Excel files. The file needs to have a Named Range defined. This - unless already defined in your source files - makes it a huge problem. Big enough to have the Excel files converted to csv with some external script - and then loading it as a list of files (via indirect load mentioned by @maggie).

Answer 5

You can use the ODBC driver to read the excel file. If you have multiple file with same structure. I will suggest you to follow below approach:

1. Change the file into .csv by using suitable scripting language (perl ,python). 2.use indirect file load method. you can give file names in a separate file. this way you can process all files in one go.

Hope this helps.
