Introduction
Exporting data from FoxPro to CSV is a straightforward process that enables you to use your data in a variety of other applications. This guide will walk you through the steps needed to make this transition efficiently.
We'll show you the necessary commands within FoxPro to ensure your data is exported correctly. Additionally, we'll explore how Sourcetable lets you analyze your exported data with AI in a simple to use spreadsheet.
Exporting Data to CSV Format from FoxPro
- To export a FoxPro cursor to a CSV file, you can use the <code>COPY TO</code> command. This command allows you to specify the path to the CSV file and the type of file to create. For example, you can use <code>COPY TO "c:\path\to\file.csv" TYPE DELIMITED</code> to export the cursor to a CSV file.
- FoxPro automatically chooses a delimiter when using the <code>COPY TO</code> command with <code>TYPE DELIMITED</code>. By default, every column in the cursor is delimited. However, this default behavior can sometimes lead to data corruption or loss of information, especially with dates and numerical values.
- Using <code>COPY TO "c:\path\to\file.csv" TYPE DELIMITED</code> may result in data issues such as blank dates, zero numerical values, and skipped records. These problems can arise due to bugs in older versions of Visual FoxPro. To mitigate these issues, it is advisable to browse the data before copying it to CSV to ensure its correctness.
- An alternative method involves exporting the data to an Excel file using <code>COPY TO "c:\path\to\file.xls" TYPE XL5</code> and then converting the Excel file to CSV. This approach often yields better results than copying directly to CSV. Some users may also find it beneficial to use a custom CSV exporter for more control over the output.
- When exporting data to CSV, always verify the source data first. Using the BROWSE command before executing the COPY TO command can help identify any potential issues with the data. Additionally, consider using the <code>TYPE CSV</code> option instead of <code>TYPE DELIMITED</code> to avoid some of the common pitfalls associated with the default settings.

How to Export Your Data to CSV Format from FoxPro
Using the COPY TO Command
To export data from FoxPro to CSV format, the primary method is to use the COPY TO command. This command is straightforward and allows you to specify the filename and the desired output format. Utilizing TYPE CSV or TYPE DELIMITED can generate a CSV file directly from a cursor.
Basic Syntax
Use the following command to export data to a CSV file:
COPY TO "c:\path\to\file.csv" TYPE DELIMITED
or
COPY TO "c:\path\to\file.csv" TYPE CSV
Issues with Direct CSV Export
Although the COPY TO command is convenient, exporting directly to CSV using TYPE DELIMITED or TYPE CSV may result in various issues. Dates might be blank, numerical values could be set to 0, and some records might be skipped. This can affect the integrity of the exported data.
Recommended Approach: Export to XLS and Convert
To avoid issues associated with direct CSV export, it is recommended to first export the cursor to an XLS file using the TYPE XL5 option then convert the XLS file to a CSV format using a different tool. This approach works better and ensures the data integrity is maintained.
Use the following command to export data to an XLS file:
COPY TO "c:\path\to\file.xls" TYPE XL5
Summary
While COPY TO "filename.csv" TYPE CSV or TYPE DELIMITED can be used for exporting data to CSV in FoxPro, they may lead to errors in the data. For more reliable results, export first to an XLS file using TYPE XL5 and then convert the XLS to CSV.
