- Creating new spreadsheets in ODS format
- Converting between ODS, XLSX, CSV, PDF formats
- Automating data processing and analysis
- Creating formulas, charts, and pivot tables
- Batch processing spreadsheet operations
Core Capabilities
1. Spreadsheet Creation
- Create new ODS spreadsheets from scratch
- Generate spreadsheets from templates
- Create data entry forms
- Build dashboards and reports
2. Format Conversion
- ODS to other formats: XLSX, CSV, PDF, HTML
- Other formats to ODS: XLSX, XLS, CSV, DBF
- Batch conversion of multiple files
3. Data Automation
- Formula automation and calculations
- Data import from CSV, database, APIs
- Data export to various formats
- Batch data processing
4. Data Analysis
- Pivot tables and data summarization
- Statistical functions and analysis
- Data validation and filtering
- Conditional formatting
5. Integration
- Command-line automation via soffice
- Python scripting with UNO
- Database connectivity
Workflows
Creating a New Spreadsheet
Method 1: Command-Line
soffice --calc template.ods
Method 2: Python with UNO
import uno
def create_spreadsheet():
local_ctx = uno.getComponentContext()
resolver = local_ctx.ServiceManager.createInstanceWithContext(
"com.sun.star.bridge.UnoUrlResolver", local_ctx
)
ctx = resolver.resolve(
"uno:socket,host=localhost,port=8100;urp;StarOffice.ComponentContext"
)
smgr = ctx.ServiceManager
doc = smgr.createInstanceWithContext("com.sun.star.sheet.SpreadsheetDocument", ctx)
sheets = doc.getSheets()
sheet = sheets.getByIndex(0)
cell = sheet.getCellByPosition(0, 0)
cell.setString("Hello from LibreOffice Calc!")
doc.storeToURL("file:///path/to/spreadsheet.ods", ())
doc.close(True)
Method 3: Using ezodf
import ezodf
doc = ezodf.newdoc('ods', 'spreadsheet.ods')
sheet = doc.sheets[0]
sheet['A1'].set_value('Hello')
sheet['B1'].set_value('World')
doc.save()
Converting Spreadsheets
# ODS to XLSX
soffice --headless --convert-to xlsx spreadsheet.ods
# ODS to CSV
soffice --headless --convert-to csv spreadsheet.ods
# ODS to PDF
soffice --headless --convert-to pdf spreadsheet.ods
# XLSX to ODS
soffice --headless --convert-to ods spreadsheet.xlsx
# Batch convert
for file in *.ods; do
soffice --headless --convert-to xlsx "$file"
done
Formula Automation
import uno
def create_formula_spreadsheet():
local_ctx = uno.getComponentContext()
resolver = local_ctx.ServiceManager.createInstanceWithContext(
"com.sun.star.bridge.UnoUrlResolver", local_ctx
)
ctx = resolver.resolve(
"uno:socket,host=localhost,port=8100;urp;StarOffice.ComponentContext"
)
smgr = ctx.ServiceManager
doc = smgr.createInstanceWithContext("com.sun.star.sheet.SpreadsheetDocument", ctx)
sheet = doc.getSheets().getByIndex(0)
sheet.getCellByPosition(0, 0).setDoubleValue(100)
sheet.getCellByPosition(0, 1).setDoubleValue(200)
cell = sheet.getCellByPosition(0, 2)
cell.setFormula("SUM(A1:A2)")
doc.storeToURL("file:///path/to/formulas.ods", ())
doc.close(True)
Format Conversion Reference
Supported Input Formats
- ODS (native), XLSX, XLS, CSV, DBF, HTML
Supported Output Formats
- ODS, XLSX, XLS, CSV, PDF, HTML
Command-Line Reference
soffice --headless
soffice --headless --convert-to <format> <file>
soffice --calc # Calc
Python Libraries
pip install ezodf # ODS handling
pip install odfpy # ODF manipulation
pip install pandas # Data analysis
Best Practices
- Use named ranges for clarity
- Document complex formulas
- Use data validation for input control
- Create templates for recurring reports
- Store ODS source files in version control
- Test conversions thoroughly
- Use CSV for data exchange
- Handle conversion failures gracefully
Troubleshooting
Cannot open socket
killall soffice.bin
soffice --headless --accept="socket,host=localhost,port=8100;urp;"
