Work with the file you already have
Open a compatible CSV, spreadsheet, image, document or file set and start with the actual task instead of converting everything first.
Direct access
Browser tools for files, data, images, documents, text and lists.
Choose a focused tool for the job in front of you: clean or compare data, inspect file sets, convert images, extract values, prepare a delivery or make a quick selection. Search by task, input or tool name; no workflow, account or onboarding is required.
Files
Inspect sets, compare releases, reconcile records and test explicit readiness rules.
Folder Sanity Check
Inspect a folder or file set for empty files, duplicate names and consistency signals.
File Set Change Check
Compare baseline and current file sets and review added, removed, changed and uncertain items.
Data ↔ File Matcher
Match data records to files without silently promoting ambiguous relationships.
File Readiness Check
Test a file set against the explicit delivery requirements you enter.
Bulk Filename Fixer
Preview safer normalized or numbered filenames and create renamed copies without touching the originals.
Asset Manifest Generator
Export file facts, SHA-256 fingerprints and image dimensions where available.
Sequence Repair
Detect gaps and duplicate numbers, preview a contiguous renumbering plan and create renamed copies.
Small tools that stay focused
TaskThimble is built for digital jobs that are too specific for a search answer but too small to justify a heavyweight application. Most tools work directly in the browser and keep active input local where practical.
Preview before changing anything
Checks and transformations are designed to show evidence, options or a preview before a new output is created. Source files remain unchanged by default.
Use deterministic rules where they are enough
Cleaning, comparison, extraction, conversion and validation use explicit browser-based logic when that is more reliable than adding AI.
Continue only when another step helps
A result can move into a compatible TaskThimble tool without forcing every small task into a workflow.
Images
Review whole image sets and catalog asset coverage.
Image Set Check
Review set-level differences and optional explicit image-size requirements.
Listing Pack Check
Check product-record asset coverage and image requirements together.
Image Set Harmonizer
Create new copies on a consistent canvas without cropping or silent upscaling.

Convert still-image copies to PNG, JPEG or WebP locally.
Remove Image Metadata
Create re-encoded still-image copies without ordinary embedded source metadata.
Image Contact Sheet + Review
Create one PNG review sheet and surface optional set-relative visual flags.
Image Version Compare
Compare two revisions by dimensions and normalized pixel difference without judging correctness.
Similar Image Finder
Find visually similar candidate pairs with a lightweight perceptual hash and review them before acting.

CSV Preflight
Check common structural and data-quality issues before import.

Join CSV by Key
Combine two tables using a shared key.
Split CSV
Split a table into smaller outputs.
Remove Duplicate CSV Rows
Remove repeated records deterministically.
JSON Formatter & Inspector
Validate and format JSON, and turn object arrays into a table.
Excel XLSX to Table
Choose a worksheet and continue with browser-local table tools.
Table Lab
Open compatible data directly and filter, sort, select, rename or reorder columns.
Spreadsheet Relationship Check
Check whether references in one table point to unique identifiers in another.
Export Table
Download the current table as XLSX, CSV, TSV or JSON.
Make This File Compatible
Map source data to a target CSV or TSV structure with explicit choices.
Documents
Check document delivery packs at the file/container level.
Text & lists
Extract useful values, clean lists, compare columns and count occurrences.

URL Extractor
Extract web links from copied text.
Number Extractor
