How can I add custom Excel formatting to the converted file in the CSV to Excel Converter?
You can customize the Excel formatting by modifying the convert_csv
function in the routes.py
file. Here's an example of how to add basic formatting:
```python @app.route("/convert", methods=["POST"]) def convert_csv(): try: csv_text = request.json.get("csv_text", "") df = pd.read_csv(io.StringIO(csv_text))
excel_buffer = io.BytesIO()
with pd.ExcelWriter(excel_buffer, engine='xlsxwriter') as writer:
df.to_excel(writer, index=False, sheet_name='Sheet1')
# Get the xlsxwriter workbook and worksheet objects
workbook = writer.book
worksheet = writer.sheets['Sheet1']
# Add a format for the header
header_format = workbook.add_format({
'bold': True,
'text_wrap': True,
'valign': 'top',
'fg_color': '#D7E4BC',
'border': 1
})
# Write the column headers with the format
for col_num, value in enumerate(df.columns.values):
worksheet.write(0, col_num, value, header_format)
excel_buffer.seek(0)
return send_file(excel_buffer, mimetype='application/vnd.openxmlformats-officedocument.spreadsheetml.sheet',
as_attachment=True, download_name='converted.xlsx')
except Exception as e:
logger.error(f"Error converting CSV: {str(e)}")
return jsonify({"error": str(e)}), 400
```
This code adds a formatted header row to the Excel file during the conversion process.
How can I extend the CSV to Excel Converter to handle larger file sizes?
To handle larger file sizes in the CSV to Excel Converter, you can implement chunked processing and streaming. Here's an example of how to modify the convert_csv
function to handle larger files:
```python from flask import Response import csv
@app.route("/convert", methods=["POST"]) def convert_csv(): try: csv_text = request.json.get("csv_text", "") csv_file = io.StringIO(csv_text) csv_reader = csv.reader(csv_file)
def generate():
excel_buffer = io.BytesIO()
workbook = xlsxwriter.Workbook(excel_buffer, {'in_memory': True})
worksheet = workbook.add_worksheet()
for row_index, row in enumerate(csv_reader):
for col_index, cell in enumerate(row):
worksheet.write(row_index, col_index, cell)
if row_index % 1000 == 0: # Flush every 1000 rows
excel_buffer.seek(0)
data = excel_buffer.getvalue()
excel_buffer.seek(0)
excel_buffer.truncate()
yield data
workbook.close()
excel_buffer.seek(0)
yield excel_buffer.getvalue()
return Response(generate(), mimetype='application/vnd.openxmlformats-officedocument.spreadsheetml.sheet',
headers={"Content-Disposition": "attachment;filename=converted.xlsx"})
except Exception as e:
logger.error(f"Error converting CSV: {str(e)}")
return jsonify({"error": str(e)}), 400
```
This implementation uses a generator function to process the CSV data in chunks and stream the Excel file to the client, allowing for better memory management when dealing with large files in the CSV to Excel Converter.
