CSVReader vs BigSplice

Open, view, and edit CSV & TSV files right on your iPhone. No computer or spreadsheet app needed. CSV Reader is a fast, simple tool for working with tabular data on the go. Check an export from work, fix a typo in a data file, or find one row in thousands in just a few taps. KEY FEATURES • Edit CSV and TSV files Change cell values directly and keep your data up to date wherever you are. • No more garbled text Encodings are detected automatically, so files open correctly. That includes UTF-8, UTF-16, Windows-1252 (Excel on Windows), ISO-8859-1 (Latin-1), Mac Roman, and many more. Accented letters, curly quotes, and symbols show up exactly as they should. • Sort any column instantly Tap a column to sort in ascending or descending order. • Powerful per-column filters Set conditions on each column to narrow thousands of rows down to exactly what you need. • Easy-to-read layout Columns resize automatically to fit their content, so your data stays clear and readable. Whether you're a developer, analyst, or anyone who gets CSV files by email, CSV Reader makes handling data on mobile easy.

BigSplice is the spreadsheet for data that is too big for a spreadsheet. A month of IIS or nginx logs. A 4 GB CSV export. A Kaggle competition dataset with fifty million rows. Where other apps choke at a few hundred thousand rows, BigSplice opens multi-gigabyte CSV, Excel and JSON files in seconds and runs entirely on your iPhone, iPad and Mac. Sort, filter, pivot, chart, write formulas and ask questions in plain English. Nothing is uploaded anywhere. SERVER LOGS, FINALLY READABLE Drop in a folder of IIS, nginx or Apache logs — zipped or not — and BigSplice turns them into one sheet you can actually work with: • Pivot a month of traffic in seconds: requests by status code (how many 500s? which URLs threw 404s?), by hour, by client IP, by user agent • Search every file at once: an email address, a session id, an IP — BigSplice also matches the URL-encoded and case variants, so "@outlook.com" finds "%40outlook.com" inside query strings • Ask in plain English: "which endpoints were slowest yesterday?", "how many 500 errors per hour this week?", "top 10 IPs hitting /login" — answered from your data, on your device • Formats: IIS/W3C (#Fields), nginx & Apache access logs, syslog, plain text logs; .log, .gz, .zip. A folder becomes one sheet with a file column, and new files show up when you reopen it • Chart it in one tap: count the 500s by hour and see the spike COMPETITION-SIZE DATASETS Built for the files data scientists actually download — Kaggle competition data, open-data dumps, taxi-trip and sensor records, warehouse exports: • Open a multi-gigabyte CSV and start scrolling in seconds; tens of millions of rows stay smooth • Explore before you model: column filters with value lists, sort on any column, search that highlights every hit • Group and aggregate with drag-and-drop pivot tables — counts, sums, averages by any column — then chart the result • Check a join or a leaky feature in plain English: "how many rows per label?", "average fare by hour and passenger count", "which customer ids appear more than once?" • Put the train, test and submission files in one folder and ask across all of them at once • Export the cleaned result to CSV or Excel REAL SPREADSHEET TOOLS • Formulas with SUM, AVERAGE, IF, VLOOKUP and hundreds more, plus AutoSum. Edit cells in place. ASK YOUR DATA • Ask a question — "which region sold the most last quarter?" — and get an answer worked out from your actual data. • Runs with the built-in model on your device or its larger private cloud model (both use Apple Intelligence), with a large model you download, or with a model server you run yourself. Every query is shown to you and needs your approval before it runs. • Ask it to build a pivot or summary table and it appears as a new sheet. • New here? Load a sample dataset — server logs, city records or taxi trips — in one tap. CHARTS IN ONE TAP • Any pivot or Ask answer becomes a bar, line or area chart — one tap, no setup. Dates on the axis are recognised automatically. IMPORT FROM ANYWHERE • Files app, iCloud Drive, web links, ZIP archives. • Your own Amazon S3, Google Cloud Storage or Azure buckets — browse folders, open files directly. Credentials stay in your device's Keychain. PRIVATE BY DESIGN • No account, no sign-in, no analytics. Your files never leave your device unless you choose to share them. • Optionally share sheets with another device over Wi‑Fi or Tailscale, protected by a pairing code.
