Hello everyone.

I'm getting this error while generatin an 12k rows XLSX.

This just happens with this kind of 'huge' XLSX files. For example, for those with 8k lines there's no problem.
Thanks in advance for any help.

Hi i tried the the ruby code in the documentation. the "output.xlsx" file created to my project file. is this possible to trigger on the browser? for example the user click the button and then the "output.xlsx(with password)" file will downloaded?

Running the following command produces an empty excel file when using the attached .csv file.

secure-spreadsheet --password 123 < ../tmp/dayzz_leads.csv > ../tmp/dayzz_leads.xlsx

I am on MacOS 10.15.7 using [email protected] on [email protected]
This also happened on an older versions and newer versions of node.
Encrypting a simple file with just a,b works fine.

Input: dayzz_leads.csv.txt (had to add .txt extension since github does not allow csv files).
Output: dayzz_leads.xlsx

Thanks

Hello,

I am facing issue while trying to run the secure-spreadsheet codes through Crontab/Cronjobs. I've created both the version of the codes, i.e. PHP and Python to test the issue.

My python file contains below code

#!/usr/bin/env python3.6
import subprocess

csv_str = b'awesome,csv'

result = subprocess.check_output(['/usr/local/bin/secure-spreadsheet', '--password', 'secret'], input=csv_str)

with open('output.xlsx', 'wb') as f:
    f.write(result)

My PHP file contains below code

<?php
$csv_str = "this,is,a,test";

$descriptorspec = array(
  0 => array("pipe", "r"),
  1 => array("pipe", "w")
);

$process = proc_open("/usr/local/bin/secure-spreadsheet --password secret", $descriptorspec, $pipes);

if (is_resource($process)) {
    fwrite($pipes[0], $csv_str);
    fclose($pipes[0]);

    $result = stream_get_contents($pipes[1]);
    fclose($pipes[1]);

    $return_value = proc_close($process);
    if ($return_value != 0) {
      die("Command failed");
    }
}

$file = fopen("output.xlsx", "w") or die("Unable to open file!");
fwrite($file, $result);
fclose($file);

Though I am able to simply run the below commands straight by logging in via SSH into server, and it generates the XLSX files successfully, it doesn't work when I am trying to run both the files through cronjobs.

python test.py
php test.php

I've setup below crontabs

# m h  dom mon dow   command
10 17  * * * /usr/bin/php /home/ubuntu/xxxx.com/wp-content/plugins/xxxx/tmp/test.php  >> /home/ubuntu/xxxx.com/wp-content/plugins/xxxx-automated-registration-data-share/tmp/log.log 2>&1
07 17 * * * /usr/bin/python3.6 /home/ubuntu/xxxx.com/wp-content/plugins/xxxx-automated-registration-data-share/tmp/test.py  >> /home/ubuntu/xxxx.com/wp-content/plugins/xxxx-automated-registration-data-share/tmp/log.log 2>&1

When the cronjobs are done running, it returns below output, in both the cases, i.e. PHP and Python:

/usr/local/lib/node_modules/secure-spreadsheet/node_modules/get-stdin/index.js:13
        for await (const chunk of stdin) {

Please let me know how to proceed further. My agenda is to simply generate the password protected excel sheet.

Thanks,
Jay.

Hello,

Would you be able to add XLSM support to this project? I forked your code a few weeks ago to add it, and it has been working fine. There are no additional changes needed other than checking for 'xlsm' in addition to 'xlsx' in this line of src/cli.js:

if (options.inputFormat == "xlsx") {

With the new release of 'csv-parse' the module stopped working with the error:
When trying to execute cli.js directly from the repository

(node:5984) ExperimentalWarning: The ESM module loader is experimental.
file:///C:/Dev/secure-spreadsheet/src/cli.js:5
import parse from 'csv-parse';
       ^^^^^
SyntaxError: The requested module 'csv-parse' does not provide an export named 'default'

    at async ModuleJob.run (internal/modules/esm/module_job.js:136:20)
    at async Loader.import (internal/modules/esm/loader.js:179:24)

When using the installed module:

root@6929069cb676:/src/pkg/cryptography/encrypter# echo "var,value\ntemp,10\n" | secure-spreadsheet --password secret > output.xlsx
Error: parse is not a function

This is because 16 hours before csv-parse published a mayor upgrade 5.0.1. That is not compatible anymore.

I propose to fix the dependencies version with ^ in order to prevent the module to update a mayor and possible not compatible version of the dependancies.

I have installed library in my local system. After that I tried to run secure-spreadsheet command but it didn't found. can anyone help to fix it?

The blank file is created when the service is run with cronjob. I couldn't find the reason.

I was run below script ( save xlsx bytes to BytesIO and use it for input )

import pandas as pd
from subprocess import check_output
from io import BytesIO
df = pd.read_csv("SalesJan2009.csv")

bio = BytesIO()

with pd.ExcelWriter(bio,'openpyxl') as xlw:
    df.to_excel(xlw, sheet_name="yallacha")

print(check_output(args=['secure-spreadsheet','--password','sectet','--input-format','xlsx'],input=bio.getvalue()))

and I have got error below. and got exception "subprocess.CalledProcessError"

+) When I change pd.ExcelWriter's engine to xlsxwiter, secure-spreadsheet works correctly. but when engine of pd.ExcelWriter id "openpyxl", secure-spreadsheet does not works

Hi,
I am trying to use secure-spreadsheet with my PHP scripts to encrypt an excel sheet,
when using the secure-spreadsheet as a command in cmd it works correctly,
secure-spreadsheet --password password < C:\wamp64\www\test.csv > C:\wamp64\www\test.xlsx

but when using PHP script it generates the file, but it can't open as the following image:

this the PHP script:
$infilepath = 'C:\wamp64\www\test.csv'; $outfilepath = 'C:\wamp64\www\test.xlsx'; $encryptionPassword = 'password'; //$encryptCommand = "type $infilepath | secure-spreadsheet --password $encryptionPassword > $outfilepath"; $encryptCommand = "secure-spreadsheet --password $encryptionPassword < $infilepath > $outfilepath"; exec($encryptCommand); //system($encryptCommand);

I will be appreciated for any guides to work around this issue.

Hello,

Not sure if it would be out of scope for this project, but would you be able to change it so that the CLI commands allows you to just convert CSV to XLSX without a password.

I know this is a secure spreadsheet package, however I would have expected if the --password option was left out, it would have just directly converted the document. However it generates a 0kb XLSX file.
