CLI

casparser also comes with a command-line interface that prints summary of parsed portfolio in a wide variety of formats.

Usage: casparser [-o output_file.json|output_file.csv] [-p password] [-s] [-a] CAS_PDF_FILE

  -o, --output FILE               Output file path. Saves the parsed data as json or csv
                                  depending on the file extension. For other extensions, the
                                  summary output is saved. [See note below]

  -s, --summary                   Print Summary of transactions parsed.
  -p PASSWORD                     CAS password
  -a, --include-all               Include schemes with zero valuation in the
                                  summary output
  -g, --gains                     Generate Capital Gains Report (BETA)
  --gains-112a ask|FY2020-21      Generate Capital Gains Report - 112A format for
                                  a given financial year - Use 'ask' for a prompt
                                  from available options (BETA)
  --force-pdfminer                Force PDFMiner parser even if MuPDF is
                                  detected

  --version                       Show the version and exit.
  -h, --help                      Show this message and exit.

CLI examples

# Print portfolio summary
casparser /path/to/cas.pdf -p password

# Print portfolio and capital gains summary
casparser /path/to/cas.pdf -p password -g

# Save parsed data as a json file
casparser /path/to/cas.pdf -p password -o pdf_parsed.json

# Save parsed data as a csv file
casparser /path/to/cas.pdf -p password -o pdf_parsed.csv

# Save capital gains transactions in csv files (pdf_parsed-gains-summary.csv and
# pdf_parsed-gains-detailed.csv)
casparser /path/to/cas.pdf -p password -g -o pdf_parsed.csv

Note: casparser cli supports two special output file formats [-o file.json / file.csv]

1. json - complete parsed data is exported in json format (including investor info)
2. csv - Summary info is exported in csv format if the input file is a summary statement or if a summary flag (-s/--summary) is passed as argument to the CLI. Otherwise, full transaction history is included in the export. If -g flag is present, two additional files '{basename}-gains-summary.csv', '{basename}-gains-detailed.csv' are created with the capital-gains data.
3. any other extension - The summary table is saved in the file.

Demo

ISIN & AMFI code support

Since v0.4.3, casparser includes support for identifying ISIN and AMFI code for the parsed schemes via the helper module casparser-isin. If the parser fails to assign ISIN or AMFI codes to a scheme, try updating the local ISIN database by

casparser-isin --update

If it still fails, please raise an issue at casparser-isin with the failing scheme name(s).
