cxlsx_to_csv's Introduction

cxlsx_to_csv

cxlsx_to_csv is a simple converter of XLSX Excel 2007 files (a.k.a. Open Office XML) to CSV

FEATURES:

Simple converter, pretty fast as done in C.
Only depends on miniz (included for convenience) and one XML library, that can be either Expat or Parsifal or Mini-XML.

The XLSX format is just a glorified ZIP (that I open thanks to miniz), containing a set of XML files (that I parse thanks to Expat or Mini-XML or Parsifal). Notice that Excel stores dates as the number of days that have elapsed since 1-January-1900 (the Excel Epoch), and this program exports dates simply as the floating point value they are stored.

SYNOPSIS:

cxlsx_to_csv -if input.xlsx [-sh sheet_id] [-of output.csv]
    input.xlsx  input spreadsheet in Excel 2007 format (Office Open XML)
    sheet_id    number of the sheet within the workbook (default is first one)
    output.csv  output CSV file (default is STDOUT)

COMPILATION:

It is possible to choose at compilation time from a number of XML parsing libraries:

Expat
cc -DCONFIG_EXPAT -o cxlsx_to_csv cxlsx_to_csv.c -l expat
Parsifal
cc -DCONFIG_PARSIFAL -o cxlsx_to_csv cxlsx_to_csv.c -lparsifal
Mini-XML
cc -DCONFIG_MXML -o cxlsx_to_csv cxlsx_to_csv.c -l mxml

If you choose no XML library, then you may benchmark the time used exclusively by the decompressing step:
cc -o cxlsx_to_csv cxlsx_to_csv.c

SPEED COMPARISON:

Tested under Ubuntu 15.10 on an Intel i3-3217U CPU @ 1.80GHz, with a Crucial CT120M500 SSD.
Locale set to LC_ALL=C.UTF-8
The input spreadsheet a.xlsx has 48665 rows and 46 columns, and weights 9165KB.

Enh: Convert only a range of cells

Many spreadsheets have some header rows describing the sheet information, and occasionally some trailer rows with version information or counts/sums.
It might be convenient to to convert to CSV just an specific range of cells in order to exclude these header/trailer rows.
