Learn about the source and target file formats to understand what happens during conversion.

Source Format

CSV File

text/csv

CSV (Comma-Separated Values) is a plain-text tabular data format where each line represents a row and values are separated by commas. It is the most universal format for exchanging structured data between databases, spreadsheets, and programming languages. CSV files contain only raw data with no formatting, types, or structural hierarchy.

Advantages

  • Universal compatibility with virtually every data tool, database, and programming language
  • Human-readable plain text that can be inspected and edited in any text editor
  • Extremely lightweight with minimal overhead beyond the raw data

Limitations

  • No standard for data types, null values, or nested structures
  • Commas within values require quoting, and inconsistent quoting causes parsing errors
  • No support for multiple tables, sheets, or relational data in a single file

Common Uses

  • Data export and import between databases and applications
  • Data science datasets and machine learning training data
  • Spreadsheet data interchange and bulk data migration

Target Format

OpenDocument Spreadsheet

application/vnd.oasis.opendocument.spreadsheet

ODS (OpenDocument Spreadsheet) is an open-standard tabular data format that stores structured data with formatting, formulas, and multiple sheets in a ZIP-compressed XML container. It provides similar capabilities to XLSX but as a vendor-neutral open standard. ODS is the native format for LibreOffice Calc and is supported by most spreadsheet applications.

Advantages

  • Open standard not controlled by any single software vendor
  • Supports multiple sheets, formulas, formatting, and data types
  • Free to implement with no licensing restrictions

Limitations

  • Less widely used in business environments than XLSX
  • Some Excel-specific formulas and features may not convert perfectly
  • Fewer data processing libraries and tools compared to XLSX and CSV

Common Uses

  • Open-source spreadsheet data in LibreOffice and OpenOffice
  • Government and public sector data requiring open format compliance
  • Cross-platform structured data exchange without Microsoft dependency
