namespace AsposeCellsCloudTutorial
{
    class Program
    {
        static void Main(string[] args)
        {
            // Configure authentication
            var clientId = "YOUR_CLIENT_ID";
            var clientSecret = "YOUR_CLIENT_SECRET";
            var api = new CellsApi(clientId, clientSecret);
            
            // Specify file name
            var name = "sample.xlsx";
            
            // Create autofit options
            var options = new AutoFitterOptions
            {
                AutoFitMergedCells = true,  // Fit merged cells
                IgnoreHidden = true  // Skip hidden content
            };
            
            // Create a request to auto-fit columns
            var request = new PostAutofitWorkbookColumnsRequest
            {
                Name = name,
                AutoFitterOptions = options
            };
            
            try
            {
                // Execute the request
                var response = api.PostAutofitWorkbookColumns(request);
                
                // Check if the operation was successful
                Console.WriteLine($"Success! Columns in '{name}' have been auto-fitted.");
                
                // You can download the modified file using:
                // var downloadRequest = new DownloadFileRequest(name);
                // api.DownloadFile(downloadRequest);
            }
            catch (Exception ex)
            {
                Console.WriteLine($"Error auto-fitting columns: {ex.Message}");
            }
        }
    }
}

Specifying Column Ranges

If you want to auto-fit only specific columns, you can specify start and end column indices:

# Tutorial Code Example - Auto-fitting Specific Columns
import asposecellscloud
from asposecellscloud.apis.cells_api import CellsApi
from asposecellscloud.models import *
from asposecellscloud.requests import *

# Configure authentication as shown previously
# ...

# Create a request to auto-fit specific columns (e.g., columns 1 to 5)
request = PostAutofitWorkbookColumnsRequest(
    name=name,
    auto_fitter_options=options,
    start_column=1,  # Column B (0-based index)
    end_column=5     # Column F
)

# Execute the request
response = api.post_autofit_workbook_columns(request)

2. Auto-fitting Rows in a Workbook

Similar to columns, you can auto-fit rows to ensure optimal height based on content.

Try It Yourself: Auto-fitting Rows

Follow these steps to auto-fit rows in an Excel file:

Upload your workbook to cloud storage
Make the API request to auto-fit rows
Download and verify the optimized workbook

Using cURL

curl -X POST "https://api.aspose.cloud/v3.0/cells/sample.xlsx/autofitrows" \
-H "accept: application/json" \
-H "authorization: Bearer YOUR_ACCESS_TOKEN" \
-H "Content-Type: application/json" \
-d '{"AutoFitMergedCells":true, "IgnoreHidden":true}'

Python Example

# Tutorial Code Example - Auto-fitting Rows in a Workbook
import asposecellscloud
from asposecellscloud.apis.cells_api import CellsApi
from asposecellscloud.models import *
from asposecellscloud.requests import *

# Configure authentication
client_id = "YOUR_CLIENT_ID"
client_secret = "YOUR_CLIENT_SECRET"
api = CellsApi(client_id, client_secret)

# Specify file name
name = "sample.xlsx"

# Create autofit options
options = AutoFitterOptions(
    auto_fit_merged_cells=True,  # Fit merged cells
    ignore_hidden=True  # Skip hidden content
)

# Create a request to auto-fit rows
request = PostAutofitWorkbookRowsRequest(
    name=name,
    auto_fitter_options=options
)

# Execute the request
response = api.post_autofit_workbook_rows(request)

# Check if the operation was successful
if response.code == 200:
    print(f"Success! Rows in '{name}' have been auto-fitted.")
else:
    print(f"Error auto-fitting rows: {response.status}")

Specifying Row Ranges

If you want to auto-fit only specific rows, you can specify start and end row indices:

# Tutorial Code Example - Auto-fitting Specific Rows
import asposecellscloud
from asposecellscloud.apis.cells_api import CellsApi
from asposecellscloud.models import *
from asposecellscloud.requests import *

# Configure authentication as shown previously
# ...

# Create a request to auto-fit specific rows (e.g., rows 1 to 10)
request = PostAutofitWorkbookRowsRequest(
    name=name,
    auto_fitter_options=options,
    start_row=1,    # Row 2 (0-based index)
    end_row=10      # Row 11
)

# Execute the request
response = api.post_autofit_workbook_rows(request)

3. Advanced AutoFit Options

Aspose.Cells Cloud provides several options to control auto-fitting behavior. These options are specified through the AutoFitterOptions object:

Option	Description
`auto_fit_merged_cells`	When true, merged cells will be resized to display all content
`ignore_hidden`	When true, hidden rows/columns will not be considered
`only_auto`	When true, only cells that have AutoFit enabled will be adjusted

Example with All Options

# Tutorial Code Example - Advanced Auto-fit Options
import asposecellscloud
from asposecellscloud.apis.cells_api import CellsApi
from asposecellscloud.models import *
from asposecellscloud.requests import *

# Configure authentication as shown previously
# ...

# Create advanced autofit options
options = AutoFitterOptions(
    auto_fit_merged_cells=True,  # Fit merged cells
    ignore_hidden=True,          # Skip hidden content
    only_auto=False              # Consider all cells, not just AutoFit-enabled ones
)

# Create a request to auto-fit columns with advanced options
request = PostAutofitWorkbookColumnsRequest(
    name=name,
    auto_fitter_options=options
)

# Execute the request
response = api.post_autofit_workbook_columns(request)

Practical Scenario: Preparing a Report for Printing

Let’s walk through a common scenario where auto-fitting is crucial - preparing a financial report for printing:

# Tutorial Code Example - Preparing a Report for Printing
import asposecellscloud
from asposecellscloud.apis.cells_api import CellsApi
from asposecellscloud.models import *
from asposecellscloud.requests import *

# Configure authentication
client_id = "YOUR_CLIENT_ID"
client_secret = "YOUR_CLIENT_SECRET"
api = CellsApi(client_id, client_secret)

# Specify file name
report_name = "quarterly_financial_report.xlsx"

# Step 1: Auto-fit all columns to ensure data is visible
column_options = AutoFitterOptions(auto_fit_merged_cells=True, ignore_hidden=True)
column_request = PostAutofitWorkbookColumnsRequest(name=report_name, auto_fitter_options=column_options)
api.post_autofit_workbook_columns(column_request)

# Step 2: Auto-fit all rows to make sure all text is visible
row_options = AutoFitterOptions(auto_fit_merged_cells=True, ignore_hidden=True)
row_request = PostAutofitWorkbookRowsRequest(name=report_name, auto_fitter_options=row_options)
api.post_autofit_workbook_rows(row_request)

print(f"Report '{report_name}' has been optimized for printing!")

Troubleshooting Tips

When working with auto-fit operations, you might encounter these common issues:

Wrapped text:
- If cells have text wrapping enabled, auto-fit might not achieve expected results
- Consider disabling text wrapping before auto-fitting
Merged cells:
- Auto-fitting merged cells can be tricky - ensure auto_fit_merged_cells is set to true
- Be aware that this might significantly increase column widths
Performance with large files:
- Auto-fitting large workbooks can be resource-intensive
- Consider auto-fitting only specific ranges instead of the entire workbook
Unexpected resizing:
- Some formulas or cell contents might cause excessive column widths
- To control this, target specific columns rather than the entire workbook

What You’ve Learned

In this tutorial, you’ve learned how to:

Auto-fit columns to optimize the width based on content
Auto-fit rows to ensure proper display of all text
Specify column and row ranges for targeted optimization
Configure advanced auto-fit options
Apply auto-fitting in a practical report preparation scenario

Further Practice

To reinforce your learning, try these exercises:

Create a script that auto-fits a workbook and then exports it to PDF
Implement column width limits while auto-fitting (hint: you might need additional API calls)
Write a program that intelligently auto-fits based on content type (e.g., different approaches for numeric data vs. text)
Create a utility that batch processes multiple workbooks, applying appropriate auto-fit settings to each
