I am trying to work with Paradox files and convert these to an Excel file.
Does anyone know how to achieve such conversion?
I wrote a small Python script to read Paradox .DB files.
But please be careful, it's not complete: some field types may not be converted (only memos AFAIK, but I'm not a Paradox expert).

You can either read a .DB file as Python objects using paradox.read('your_file.DB') or convert it to a CSV file using paradox.to_csv('your_file.DB').

How can I convert a .numbers file to an .xlsx file using the xlsx library in nodejs? The documentation states that Numbers is not included in the library by default, and you must use the xlsx.zuhl.js, xlsx.zuhl.mjs scripts. In the documentation for xlsx library there is example how to use script for exporting Numbers files, could you write an example of how you can use this script to read Numbers file format and convert it to .xlsx?
Is there any other way to convert .numbers file to .xlsx?
Using an existing SSIS package, I was trying to import .xlsx files we received from a client. I received the error message:
External table is not in the expected format
These files will open in XL
When I use XL (currently XL2010) to Save As... the file without making any changes:
The new file imports just fine
The new file is 330% the size of the original file
When changing .xlsx to .zip and investigating the contents with WinZip:
The original file only has 4 .xml files and a _rels folder (with 2 .rels files):
The new file has the expected .xlsx contents:
Does anyone know what kind of file this could be?
It would be nice to develop my SSIS package to work with these original files, without having to open and re-save each file. There are only 12 files, so if there are no other options, opening/saving each file is not that big of deal...and I could automate it with VBA going forward.
Thanks for any help anyone can provide,

There are many Excel file formats.
The file you are trying to import may have another excel format but the extension is changed to .xlsx (it could be edited by someone else) , or it could be created with a different Excel version.
There is a Third-Part application called TridNet File Identifier which is an utility designed to identify file types from their binary signatures. you can use it to specify the real extension of the specified file.
Also after a simple search on External table is not in the expected format this error is thrown when the definition (or version) of the excel files supported in the connection string is different from the file selected. Check the connection string used in the excel connection manager. It might help to identify the version of the file.
I need to read xlsx in nodejs. Xlsx contains text with accents and apostrophes and so on. Then i have to save the text in json file.
What are the best practices to perform that task?
Stage 1 - take a look at this module node-xlsx or more robust and possibly better for your needs xlsx.
Stage 2 - Writing the file to JSON - if the module can return a JSON format then great. If you use xlsx it has an option to JSON --> take a look here.
Since you may need to actually strip and/or protect special accents etc. you may need to validate the data which is returned before producing a JSON file.
As to actually writing a JSON file, there are a huge amount of NPM modules for the task.
I want to compare the data in two .csv files.Have to compare the updated data between these two .csv file using nodejs.
Is ther any possibilities to do it in Nodejs.
Thanks,I am very newbie to this.
It will be easiest using one of the following modules:
https://www.npmjs.com/package/csv
https://www.npmjs.com/package/tsv
or other that you find in:
https://www.npmjs.com/browse/keyword/csv
https://www.npmjs.com/browse/keyword/tsv
(don't worry if it's CSV or TSV - just make sure that you use the correct delimiter which is comma in your case).
I need to write a Stored Proc/ Function which reads data from a worksheet of Excel workbook. How do I do it in DB2 ? I am using AIX os.
Tried Read Excel from DB2 but wont work on my OS.
Also tried
Import from FileName.csv of DEL COMMITCOUNT 1000 insert into TableName
but invain.
You have several options, the cleanest is probably to write a Java Stored Procedure, utilising the Apache POI library, if you intend to read Excel workbooks (.xls or .xlsx) rather than plain CSV formatted text files.
Not as clean but just as effective you can write a Perl / Python / PHP script to read the file and return a line at a time, and invoke the script from a stored procedure, see: Making Operating System Calls from SQL
Its be better to convert your excel file to flat file like csv if possible. Because DB2 not natively know excel file. Its csv file that can processed natively using IMPORT, LOAD or INGEST tools from DB2
