Source File
When a company files with the SEC, it submits one or more source files that make up the filing. These files contain the raw content exactly as provided by the filer, before any summaries or transformations.
Source files can include structured formats, such as XBRL or XML, as well as text-based documents. Together, they form the complete filing as stored in the SEC’s systems.
Because source files are the original submission, they represent the most direct version of the disclosure. All rendered views, extracts, or datasets are derived from these files.
Why It Matters
Source files preserve the original disclosure exactly as filed. They are critical for verification, auditing, and accurate data extraction.
How are source files used within the SEC filing process?
Source files are the building blocks of an SEC filing. The EDGAR system stores them and uses them to generate public views and downloadable formats. Regulators rely on source files to review compliance. They serve as the official record of what was submitted.
How do source files differ from processed or rendered filings?
Rendered filings are human-readable versions created from source files. Source files contain raw structure and tagging that may not be visible in the rendered view. Data products and analytics depend on these raw files. Using source files reduces interpretation errors.
Why are source files important for data-driven analysis?
Source files enable precise data extraction and validation. Analysts can access tagged financial data, metadata, and document structure directly. This supports automation and large-scale research. Without source files, structured analysis would be limited.
Real-World Example
A developer retrieves the source files of a 10-K filing to extract XBRL-tagged financial data directly. This avoids relying on PDFs or summarized views.
