Convert CSV, TSV, and TXT to Excel with Golang via C++

Opening CSV Files

Comma Separated Values (CSV) files contain records where the values are separated by commas. Data is stored as a table where each column is separated by the comma character and quoted by the double quote character. If a field value contains a double quote character, it is escaped with a pair of double quote characters. You can also use Microsoft Excel to export spreadsheet data to CSV.

Opening CSV Files and Replacing Invalid Characters

In Excel, when a CSV file with special characters is opened, the characters are automatically replaced. The same is done by the Aspose.Cells API, as demonstrated in the code example below.

Using Preferred Parser

It is not always necessary to use default parser settings for opening CSV files. Sometimes, importing a CSV file does not create the expected output, such as when the date format is not as expected or empty fields are handled differently. For this purpose, TxtLoadOptions.PreferredParsers is available to provide your own preferred parser to parse different data types as per your requirements. The following sample code demonstrates the usage of a preferred parser.

Sample source file and output files can be downloaded from the following links for testing this feature.

Opening Text Files with Custom Separator

Text files are used to hold spreadsheet data without formatting. The file is a kind of plain text file that can have some customized delimiters.

Opening Tab-Delimited Files

Tab-delimited (Text) files contain spreadsheet data but without any formatting. Data is arranged in rows and columns like in tables and spreadsheets. Basically, a tab-delimited file is a special kind of plain text file with a tab between each column.

Opening Tab-Separated Values (TSV) Files

Tab-separated values (TSV) files contain spreadsheet data but without any formatting. It is the same as a tab-delimited file where data is arranged in rows and columns like in tables and spreadsheets.
