Installation

pip install --upgrade ezstdf

Dependencies

Features

• Can read STDF (binary, V4) and ATDF (clear text, V2) files
• Most record types are supported, unsupported ones are skipped for now
• Convert records to Pandas data frames
• Export to Excel file (requires openpyxl)

• Fast and easy to use

Examples

Parse a file:

from ezstdf.StdfReader import StdfReader
stdf = StdfReader()
stdf.parse_file("../sample_files/sample.atdf")

# each record type can now be accessed as a data frame
# example: access the File Attributes Record (FAR)
df_far = stdf.far
print(df_far)
